What is the area of rectangle?

The area of rectangle is product of length and width

Given area of rectangle is 90 ft²

given length = 8 ft + 2ₓ width

l = 8 +2 w

area = l × w

90 = (8 +2 w) × w

90= 8w +2w²

2w²+ 8w -90 =0 or w²+4w - 45 =0

On solving w= 9, -5

as width cannot be negative so w= 9

l= 8+2×9

l=26

Thus the length and width of the wall of the barn are 18, 9
