How to find the perimeter of a right triangle - SSAT Upper Level Quantitative

Using the Pythagorean Theorem, the length of the second leg can be determined.

We are given the length of the hypotenuse and one leg.

The perimeter of the triangle is the sum of the lengths of the sides.

First, we need to use the Pythagorean Theorem to find the hypotenuse of the triangle.

Now, add up all three side lengths to find the perimeter of the triangle.

First, use the Pythagorean Theorem to find the length of the hypotenuse.

Substituting in and for and (the lengths of the triangle's legs), we get:

Now, add up the three sides to find the perimeter:

In order to find the perimeter of the right triangle, we need to first find the missing length of the hypotenuse. In order to find the hypotenuse, use the Pythagorean Theorem:

, where and are the lengths of the legs of the triangle, and is the length of the hypotenuse.

Substituting in our known values:

Now that we have the lengths of all sides of the right triangle, we can calculate the perimeter:

In order to find the perimeter of the right triangle, we need to first find the missing length of the second leg. In order to find the second leg, use the Pythagorean Theorem:

, where and are the lengths of the legs of the triangle, and is the length of the hypotenuse.

Substituting in our known values:

Subtracting from each side of the equation lets us isolate the variable for which we are solving:

Now that we have the lengths of all three sides of the right triangle, we can calculate the perimeter :

We are given the length of the hypotenuse and one leg.

The perimeter of the triangle is the sum of the lengths of the sides.

A right triangle with legs 6 feet and 8 feet has hypotentuse 10 feet, as this is a right triangle that confirms to the well-known Pythagorean triple 6-8-10. The perimeter is therefore feet, or 8 yards.

We are looking for a polygon with this perimeter. Each choice is a polygon with all sides one yard long, so we want the polygon with eight sides - the regular octagon is the correct choice.

First, we need to use the Pythagorean Theorem to find the hypotenuse of the triangle.
