Question

7 inch photo was cut to fit exactly into 5 inch picture frame. what is the area, square inches of the part of the photo that was cut off? a. 2 b. 10 c. 11 d. 12 e. 24

Explanation:

Step1: Calculate the area of the original photo

Assume the original photo has length \( l = 7\) inches and width \( w = 5\) inches. The area of a rectangle is \(A = l\times w\). So the area of the original photo \(A_{original}=7\times5 = 35\) square inches.

Step2: Calculate the area of the photo that fits into the frame

Assume the frame has length \(l'= 5\) inches and width \(w' = 5\) inches (since it's a square - like fit, assuming the frame is a square of side 5 inches as it's cut to fit). The area of the photo that fits \(A_{fit}=5\times5=25\) square inches.

Step3: Calculate the area that was cut off

The area that was cut off \(A = A_{original}-A_{fit}\). Substitute the values: \(A=35 - 25=10\) square inches.
