Question

A photo is 3 inches longer that it is wide. A 2-inch border is placed around the photo making the total area of the photo and border 108in2. What are the dimensions of the photo?

Answer 1

Let the width be x.
The length is x+3;
The length with border is (x+3) + 4 = x+7;
The width with the border is x+4
Area = 108
(x+7)(x+4) = 108
=> x^2+11x-80 = 0
=> (x+16)(x-5) = 0
=> x = 5; (can't be -ve)
The dimension of the photo is 8 inch X 5 inch

Answer 2

thank you
