Then x + 3 the Now Let a be the width of the re rectangle. lengan of the rectangle. (Given) rectangle is - length x width (x+3)x x So x (x+3) = 40 [ Given in the - art3x = 40 question that = x2+37-40=0 area is 40 = x+8 x - 5x-40=0 -) 3 (2+8) -5 (2+8) = 0 5) (X + 8) (7-5)=0 either x + 8-0 x-5 - 0 ) - 8 = x=5 since length can not be negative so x=- 8 is not possible.

0 Here we take x = as the width of the re Then th 2 + 3 inches i.l, 5+3= 8 inches The width, the shorter side is 5 inches The length, the longer side is 8 inclus
