13. Shane is working with a spreadsheet on his computer. The spreadsheet will calculate the cost of the wood trim around rectangular windows based on the dimensions of the window and the price of the
wood. The following entries have been made. Shane wants to enter a formula in the last column so that
the spreadsheet will calculate the final cost of the job. Which of the following formulas should he enter?
Length of window in feet: AZ
Width of window in feet: B7
Price per foot of wood trim: C7
Cost of trim for window:
O AZ x B7 x C7
O (2 x A7 + 2 x B7) x C7
O A7 + B7 + C7
O (A7 + B7) XC7
