Greta is designing a page for the yearbook and needs to know the area of her 8 in. x 10 in. picture after she crops it. If she makes the length and width of the picture 5/8 of the original, how does the area of the picture change?

8th grade math 
Ms. Sue,
A = LW
A = 8 * 10
A = 80 sq. in.
(5/8) * 8 = 40/8 = 5
(5/8) * 10 = 50/8 = 6.25
5 * 6.25 = 31.25
