Answer» Answer: Let the width of the rectangle be X. Length of rectangle = 3x Perimeter of rectangle = 2(l+b) => 80 = 2(3x+x) => 40 = 4X => x = 40/4 => x = 10 Hence, the width is 10 m and the length is 30 m.

Answer»

Answer:

Let the width of the rectangle be X.

Length of rectangle = 3x

Perimeter of rectangle = 2(l+b)

=> 80 = 2(3x+x)

=> 40 = 4X

=> x = 40/4

=> x = 10

Hence, the width is 10 m and the length is 30 m.
