ANSWER

x = 9

EXPLANATION

We have the rectangle with width 3 ft and length (2 + x) ft.

The perimeter of the triangle is 28 ft.

The perimeter of a rectangle is given as:

P = 2(L + W)

where L = length

W = width

Therefore, we have that:

28 = 2[(2 + x) + 3]

28 = 2(2 + x + 3) = 2(x + 5)

28 = 2x + 10

=> 2x = 28 - 10 = 18

Divide through by 2:

2x/2 = 18/2

x = 9

That is the value of x.
