Question

a photograph is 5 inches by 9 inches. a frame shop charges $3.00 per inch for a silver frame. how much would it cost to buy a silver frame for the photograph? $

Explanation:

Step1: Calculate the perimeter of the photograph

The formula for the perimeter of a rectangle is \(P = 2\times(l + w)\), where \(l = 9\) inches (length) and \(w = 5\) inches (width).
\(P=2\times(9 + 5)=2\times14 = 28\) inches.

Step2: Calculate the cost of the frame

The cost per inch is \(\$3.00\). Multiply the perimeter by the cost per - inch.
\(C=28\times3\)
\(C = 84\)

Answer:

84
