Question

A rectangular room is 2 times as long as it is wide, and its perimeter is 32 meters. Find the

dimension of the room.
L=?
W=?

Answer 1

Answer: l=32/3 meters

w=16/3 meters

Explanation:

P=perimeter, l=length, w=width

P=2l+2w

32=2(2w)+2w

32=4w+2w

6w=32

w=32/6

w=16/3 meters

32=2l+2(16/3)

32=2l+32/3

(32=2l+32/3)*3

96=6l+32

6l=64

l=64/6

l=32/3 meters
