Answer:

see below for a graph

x = 4

Step-by-step explanation:

The perimeter is given by the formula ...

P = 2(L +W)

The area is given by the formula ...

A = LW

We want these two values to be equal. Using "y" for both perimeter and area, and substituting the given values for L and W, we have the equations ...

y = 2(4 +x)

y = 4x

The graph of these equations (below) shows the value of x is 4.
