Answer

1917 $in^{2}$

Work Step by Step

Find the area of each piece of metal sheet first A = l $\times$ w $A_{1}$ = 27 $\times$ 15 = 405 $in^{2}$ $A_{2}$ = 15 $\times$ 18 = 270 $in^{2}$ $A_{3}$ = 27 $\times$ 18 = 486 $in^{2}$ $A_{4}$ = 27 $\times$ 18 = 486 $in^{2}$ $A_{5}$ = 15 $\times$ 18 = 270 $in^{2}$ Then add all the areas together to find the total area A = $A_{1}$ + $A_{2}$ + $A_{3}$ + $A_{4}$ + $A_{5}$ A = 405 + 270 + 486 + 486 + 270 = 1917 $in^{2}$
