A rectangular photo has length (8) cm more than its breadth. A (2) cm wide frame is added all around and the total area is (480) square cm. What is the breadth of the photo?

Answer and explanation

Correct answer: (12) cm

The photo breadth is (x) and length is (x+8). With frame, dimensions are (x+4) and (x+12), and ((x+4)(x+12)=480) gives (x=12).
