Question 288278
Consider L as its length, and W as its width.

L is 2 inches less than 3 times W. This means that 3W subtracted by 2 would yield L:
L = 3W - 2
3W - L = 2 ... (1)

The perimeter of a rectangle is twice its width summed with twice its length:
2w + 2L = 28
simplified, by dividing with 2:
W + L = 14 ... (2)

Add up Equations (1) and (2) (in which L will be eliminated, as -L + L = 0):
.
3W - L = 2
1W + L = 14
-------------- +
4W = 16
<b>W = 4</b>
.
Because W + L = 14, L = 14 - w = 14 - 4 -> <b>L = 10</b>
