Question 900650
 You have a 3 inch by 5 inch photo that you want to enlarge,mat, and frame. You want the width of the mat to be 2 inches on all sides. You want the perimeter of the framed photo to be 44 inches. By what percent should you enlarge the photo?

photo 3 x 5

let increase in width and length be x

enlarged photo

(3+2x) & (5+2x)

width of mat = 2

length & width of frame = 

(3+2x)+4 & (5+2x)+4

7+2x, 9+2x

Perimeter = 2(l+w)

2(7+2x+9+2x)=44

16+4x= 44/2

16+4x=22
4x=22-16
4x=6
x=1.5 inch

The enlarged photo will have to be

width 3+3=6
length = 5+3=8


Area of enlarged photo = 40

Area of original = 3*5 =15

you can calculate the % increase
