36=5x

Explanation:

Here, let us designate the length of the shortest side as x. Because the other two sides are congruent, and each is double the length of the shortest side, each would be represented as 2x.

The perimeter is the sum of a figure's side measures. To calculate the perimeter:

P=a+b+c

36=x+2x+2x

36=5x

If you solve this, you will get the value

x=7.2 in

The other sides will have a measure of 14.4 in. Multiply 7.2 by 5 to check your answer, and it will be 36.
