Question

The perimeter of the triangle and the perimeter of the square are equal. Create and solve an equation to find the value of x.

Answer 1

Answer: 16

Explanation:

The perimeter of the triangle is
`2x+2x+x-8=5x-8`.

The perimeter of the square is
`4(x+2)=4x+8`.

Setting the perimeters equal to each other,

`5x-8=4x+8\\\\x-8=8\\\\x=16`
