Two rooms in a house are similar rectangles. Room A is 12 ft by 16 ft. The longer side of Room B is 4 ft shorter than twice the length of the shorter side of Room A. What are the dimensions of Room B?
The longer side of room B would be 2(12)-4 or 20. Then you would need to set up a proportion to find the shorter side of room B.
(12/16)=(x/20)
Cross multiply and you get 15.
Room A is 12 x 16 and room B is 15 x 20
