Example Question #241 : Geometry
Find the perimeter of a rectangle that has a width of 7in and a length that is three times the width.
To find the perimeter of a rectangle, we will use the following formula:
Where a, b, c, and d are the lengths of the sides of the rectangle.
Now, we know the width of the rectangle is 7in. Because it is a rectangle, the opposite side is also 7in. We also know the length of the rectangle is three times the width. Therefore, the length is 21in. Because it is a rectangle, the opposite side is also 21in.
Knowing this, we can substitute into the formula. We get
Example Question #21 : How To Find The Perimeter Of The Rectangle
Find the perimeter of a rectangle with a width of 7in and a length that is two times the width.
To find the perimeter of a rectangle, we will use the following formula:
Where a, b, c, and d are the lengths of the sides of the rectangle.
Now, we know the width of the rectangle is 7in. Because it is a rectangle, the opposite side is also 7in.
We know the length is two times the width. Therefore, the length is 14in. Because it is a rectangle, the opposite side is also 14in.
Knowing this, we can substitute into the formula. We get
Example Question #248 : Plane Geometry
Find the perimeter of a rectangle with a length of 36cm and a width that is a third of the length.
To find the perimeter of a rectangle, we will use the following formula:
Where a, b, c, and d are the lengths of the sides of the rectangle.
Now, we know the length of the rectangle is 36cm. Because it is a rectangle, the opposite side is also 36cm. We also know the width is a third of the length. Therefore, the width is 12cm. Because it is a rectangle, the opposite side is also 12cm.
Knowing this, we can substitute into the formula. We get
Example Question #249 : Plane Geometry
Find the perimeter of a rectangle with a width of 6in and a length that is four times the width.
To find the perimeter of a rectangle, we will use the following formula:
Where a, b, c, and d are the lengths of the sides of the rectangle.
Now, we know the width of the rectangle is 6in. Because it is a rectangle, the opposite side is also 6in.
We know the length is four times the width. Therefore, the length is 24in. Because it is a rectangle, the opposite side is also 24in.
Knowing this, we can substitute into the formula. We get
Example Question #31 : How To Find The Perimeter Of The Rectangle
Find the perimeter of a rectangle with a width of 2cm and a length that is six times the width.
To find the perimeter of a rectangle, we will use the following formula:
Where a, b, c, and d are the lengths of the sides of the rectangle.
Now, we know the width of the rectangle is 2cm. Because it is a rectangle, the opposite side is also 2cm.
We know the length is six times the width. Therefore, the length is 12cm. Because it is a rectangle, the opposite side is also 12cm.
Knowing this, we can substitute into the formula. We get
Example Question #32 : How To Find The Perimeter Of The Rectangle
Use the following rectangle to answer the question:
Find the perimeter.
To find the perimeter of a rectangle, we will use the following formula:
Where a, b, c, and d are the lengths of the sides of the rectangle.
Now, given the rectangle,
we can see the length is 9cm. Because it is a rectangle, the opposite side is also 9cm.
We can see the width is 7cm. Because it is a rectangle, the opposite side is also 7cm.
Knowing this, we can substitute into the formula. We get
Example Question #251 : Geometry
Find the perimeter of a rectangle with a width of 6in and a length that is three times the width.
To find the perimeter of a rectangle, we will use the following formula:
Where a, b, c, and d are the lengths of the sides of the rectangle.
Now, we know the width of the rectangle is 6in. Because it is a rectangle, the opposite side is also 6in.
We know the length is three times the width. Therefore, the length is 18in. Because it is a rectangle, the opposite side is also 18in.
So, we can substitute. We get
Example Question #34 : How To Find The Perimeter Of The Rectangle
Find the perimeter of a rectangle with a width of 4cm and a length that is three times the width.
To find the perimeter of a rectangle, we will use the following formula:
Where a, b, c, and d are the lengths of the sides of the rectangle.
Now, we know the width of the rectangle is 4cm. Because it is a rectangle, the opposite side is also 4cm.
We know the length is three times the width. Therefore, the length is 12cm. Because it is a rectangle, the opposite side is also 12cm.
So, we can substitute.
Example Question #251 : Geometry

Example Question #35 : How To Find The Perimeter Of The Rectangle
Find the perimeter of a rectangle with a length of 16cm and a width that is a quarter of the length.
To find the perimeter of a rectangle, we will use the following formula:
Where a, b, c, and d are the lengths of the sides of the rectangle.
Now, we know the length of the rectangle is 16cm. Because it is a rectangle, the opposite side is also 16cm. We also know the width of the rectangle is a quarter of the length. To find the width, we will divide 16 by 4. Therefore, the width is 4cm. Because it is a rectangle, the opposite side is also 4cm.
