The pta created a back to school backdrop and snapped polaroid pictures. the polaroid photo measures 3 inches by 4 inches. they determine that the scale is 1 inch = 1.5 feet.

1. what are the dimensions of the actual backdrop?

2. how many square feet does the backdrop cover?

1: 4.5 ft by 6 ft
2: 27 sq. ft.

First, just multiply 3 and 4 by 1.5 to convert inches to feet using the scale. You end up with 3*1.5 and 4*1.5, which equals 4.5 and 6. So the dimensions are 4.5 feet by 6 feet.

Now, just multiply 4.5 by 6 to get 27 square feet.
