What is the area of rectangle qrst if the area of rectangle defg is 108 cm and the scale factor is 3/4?

1. You have that the area of the rectangle defg is 108 cm² and the scale factor is 3/4. Therefore, the scale factor of the area of the rectangle defg  is: 
 
 =(3/4)²
 =9/16
 
 2. Keeping this on mind, you have that the area of the rectangle qrst is:
 
 A2=A1x16/9
 A2=(108 cm²x16)/9
 A2=1728 cm²/9
 A2=192 cm²
 
 The answer is: The area of the rectangle qrst is 192 cm².
