A rectangular room is 1.3 times as long as it is wide, and its perimeter is 28 meters. Find the dimension of the room.

Answer 1

L= 1.3W

28 = 2(L+W) = 2(1.3W + W) = 2(2.3W) = 4.6W

W = 28/4.6 = 14/2.3 about 6.09 in width

L = 1.3(14/2.3) = about 7.91 meters in length

round off to nearest integer and the dimensions are about 6 by 8 meters
