Answer 3

Derp. Well no, heres the explination

It will be 1/4 the original size.

original size 5"*7"=35sq "

5/2 to divide base in half = 2 1/2"

7/2 to divide height in half = 3 1/2"

then multiple 2 1/2" x 3 1/2"

first change mixed numbers to improper fractions

2 1/2 = 5/2 and 3 1/2=7/2

5/2*7/2=35/4 or 8 3/4 sq in.

So it is 1/4 the original size you can check this by multiplying 35/4*4/1 = 35 square inches the original was 35 square inches
