Answer:I would assume it is, 4in. High, by 8in. Wide

Step-by-step explanation:

6-2=4

10-2=8

Space = 8x4 = 32in2

PLEASE SEE ATTACHED IMAGE.

For this case the area is given by:

A = (22 + x) * (28 + x) = 722

Rewriting we have:

616 + 22x + 28x + x ^ 2 = 722

x ^ 2 + 50x + 616 - 722 = 0

x ^ 2 + 50x - 106 = 0

Solving the polynomial we have:

x1 = 2.04

x2 = -52.04

We take the positive root:

x = 2.04 inches:

Answer:

The width of the border to the nearest inch is:

x = 2inches
