The lengths of the sides of a rectangle window have the ratio 1.5 to 1. the area of the window is 1,350 square inches. what are the dimensions of the window? 30 inches by 45 inches 30 inches by 60 inches 30 inches by 90 inches 30 inches by 22.5 inches!

Since the ratio is 1 to 1.5, the measurement 30 inches must correspond to 1. Thus multiply 1.5 by 30. 

30*1.5 = 45

Your answer should be 45. An alternate way could be to go through all of them but for me I personally prefer this way as it is much faster and easier. Hope this helps!
