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
