Question

A rectangular room is 1.2 times as long as it is wide, and its perimeter is 28 meters. Find the

dimension of the room

Answer 1

Explanation:

We set up the 1st equation as

l=1.5w.

And the perimeter of a rectangle is

2w+2l=25

substitute the 1st equation into the second.

2w+2(1.5w)=25

2w+3w=25

5w=25 W=5

so l=1.5(5)=7.5
