Problema Solution

A rectangular room is 1.3 times as long as it is wide, and its perimeter is 30 meters. Find the dimension of the room.

Answer provided by our tutors

You have the dimensions 1.3x and x for the length and width. The equation to find the perimeter of a rectangle is 2(L + W). Plug in 1.3x for L and x for W and set it equal to 30. 

2(1.3x + x) = 30

2(2.3x) = 30

4.6x = 30

x = 6.52174 = width

length = 1.5x = 8.478260
