Question

A photographer needs a frame for an 5x7 inch picture, such that the total area is 80in^2.Calculate the width of the frame.

Answer 1

The width of the frame is 10 inches.

5x7 = 35

80-35 = 45

45/7 = 6.4

5 + 6.4 = 11.4

11.4 rounded down = 11

11 - 5 = 10

Width of the frame = 10 inches
