Question

Jordan has a photograph on his wall that is 3 in. long and 6 in. wide. He takes it to be framed which increases the length and width by 2 in. each. How does getting the picture framed change the amount of wall space needed?

My choice is B- Correct??

Choices
A. the wall needed is increased by 22in^2
B, the wall space needed is increased by 2in^2
C. the wall needed is increased by 16in^2
D. the wall space needed is increased by 4in^2

Answer 1

original area:
A = L*W
A = 6*3 = 18 in^2
new area:
A' = L'*W'
A' = 8*5 = 40 in^2
the difference between these areas is the amount of wall space needed:
40-18 = 22 in^2

thus it's A.

hope this helps~ :)
