Question

The perimeter of the trapezoid-shaped window frame is 23.59 feet. Write and solve an equation to find the unknown side length x (in

feet).

Answer 1

`5.62 + 3.65 + 5.62 + x = 23.59`

`x = 8.7 ft`

Explanation:

Perimeter of the trapezoid-shaped window = sum of all the sides of the window frame

Thus, the equation to find the unknown side length, x, would be:

✔️
`5.62 + 3.65 + 5.62 + x = 23.59`

Solve for x

`14.89 + x = 23.59`

Subtract 14.89 from each side

`14.89 + x - 14.89 = 23.59 - 14.89`

✔️
`x = 8.7 ft`
