Example Question #361 : Pre Algebra
What is the perimeter of an equilateral triangle if one side is ?
We need to know the lengths of the other sides to solve.
The perimeter is the sum of the sides of the triangle. Because the triangle is equilateral, all three sides have equal length.
That means we can take the formula
and say .
Example Question #362 : Pre Algebra
Find the perimeter of a square with a side of 4 meters.
Since each side in a square is equal, and perimeter involves adding up all of the sides, multiply 4 by 4 to get 16 meters.
Example Question #2 : How To Find The Perimeter Of A Square In Pre Algebra
What is the perimeter of a square with a side length of ?
To find the perimeter of a square you must multiply the side length by .
To do this we plug the side length into the equation
Multiply the side length, , by
to get the answer
.
Example Question #3 : How To Find The Perimeter Of A Square In Pre Algebra
What is the perimeter of the square with a side length of ?
There is insufficient information to solve.
The way to find the perimeter of a square is to add up the lengths of all the sides. Since this is a square, each side will have the same length; if one of the sides is , the other sides will be 8 as well.
From here:
Example Question #2 : How To Find The Perimeter Of A Square In Pre Algebra
What is the perimeter of a square if one side is ?
We need to know the lengths of the other sides in order to be able to solve.
Each of the sides of a square is equal. This means we can take the formula for the perimeter of a rectangle, , and say that, for a square,
.
Since the problem gives us the length of the side, we can solve:
Example Question #5 : How To Find The Perimeter Of A Square In Pre Algebra
If the perimeter of a square is , what is the length of each side?
There is insufficient information to solve
Each of the sides of a square is equal. We can take the formula for the perimeter of a rectangle, , and say that for a square,
, or
.
The problem gives us the perimeter so we can solve:
Divide both sides by :
