Question

You need to frame a picture that measures 8 by 11. If you use a mat that has a border of about 1.5 on each side what size frame should you use

11 by 10in
11 by 14in
8 by 12in
15 by 16in

Answer 1

Add the border to the initial picture.

so the new perimeter of would be the one side plus the 1.5 for each side of the picture.

so the 8 in side becomes now 8 + 1.5(left) + 1.5(right)
and the 11 becomes now 11 + 1.5(top) + 1.5(bottom

bringing the new frame to equal 11 by 14

Answer 2

you can apply this one side to the top side
