Length of a rectangle is 3m more than its width. If both length and width are decreased by 2m, the area is decreased by 18 sq.m. Find the dimensions of the rectangle.

Hi, Let the breadth is x m so length= x+3  mSo area = length×breadth= x x+3 =x2 +3x m2New length and breadth are x-2m and x+1m new area = x-2x+1=x2-x-2 m2now according to the qyestion x2+3x-x2+x+2=18 4x+2 = 18 x = 4 so lengt = x+3 = 7 m and breadth = x = 4 m
