Question

A rectangular room is 1.6 times as long as it is wide, and its perimeter is 30 meters. Find the

dimension of the room.

Answer 1

Let

L ----> the length

W ----> the width

The perimeter is equal to

P=2(L+W)

we have that

P=30 m ----> given

L=1.6W ---> given

substitute in the formula of perimeter

30=2(1.6W+W)

solve for W

15=2.6W

W=5.77 m

L=1.6*5.77

L=9.23 m

therefore

the dimensions are

length is 9.23 meters

width is 5.77 meters
