Question

A classroom is 20 feet wide. It's length is twice as long as it's breadth. Find the ratio of the length of the room to its perimeter.​

Answer 1

Answer:

length:perimeter = 1:3

Explanation:

Width = 20ft

length = 2*20ft = 40ft

So the class is a rectangle.

Perimeter of rectangle = 2(l+b) = 2(20+40)

                                      = 2*60  = 120ft

Ratio of length to perimeter = 40/120 = 1:3//
