Width: 16 meters Length: 21 meters Check: 16+21+16+21 = 74 meters which is its perimeter
Length of rectangle: 240/15 = 16 meters
A square with a side length of 16 meters has an area of 256 square meters.
Let the length be x+8 and the width be x: 2(x+8)+2x = 140 2x+16+2x = 140 4x+16 = 140 4x = 140-16 4x = 124 x = 31 Therefore: length = 31+8 = 39 meters
2l+2w=48 l=2w 2(2w)+2w=48 4w+2w=48 6w=48 w=8 l=2*8=16 So, the length is 16 meters and the width (or breadth) is 8 meters.
