Question

The length of a rectangle is three times it's width. if the perimeter of the rectangle is 80 meters , find the length and width of the rectangle.​

Answer 1

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.
