Best ResponseYou've already chosen the best response.2\[A_{\text{square}}=12 [\text{in}]\times12 [\text{in}]=144 [\text{in}]^2\] \[A_{\text{triangle}}=\frac{14 [\text{in}]\times12 [\text{in}]}2=84 [\text{in}]^2\] \[SA_{\text{square pyramid}}=A_{\text{square}}\quad+\quad4\times A_{\text{triangle}}\]
