A photograph measuring 4 inches wide and 5 inches long is enlarged to make a wall mural. If the mural
is 82 inches wide, what is the area of the mural?

 

I got 5,379.2 square inches

 

What do you get?

82/4 = 20.5 scale factor, so the length is   5 x 20.5 = 102.5

 

Area = L x W  =   82 x 102.5  in^2
