Question

A rectangular room is 4 times as long as it is wide, and its perimeter is 50 meters. Find the dimension of the room.

The length is : _____ meters and the width is _____ meters.​

Answer 1

The length is : 20 meters and the width is 5 meters.​

Explanation:

Given w is the width of the room, the length will be 4w long

P = 2(l + w)

50 = 2(4w + w)

5w = 50/2

w = 25/5

w = 5

length = 4w = 4(5) = 20
