A rectangular room is 4 times as long as it is wide, and its perimeter is 60 meters. Find the dimension of the room

Answer 1

A rectangular room is 4 times as long as it is wide, and its perimeter is 60 meters. Find the dimension of the room

Set it up as an equation using the perimeter formula (2L + 2W)

We know from the sentence that length is 4 times width so L = 4W

Plug that into the formula and solve for W

2(4W) + 2W = 60

Solve for W and plug that number back into the original problem to find the length. Check the answers.
