Question

I'm terrible at explaining answers and this is one of them...

Answer 1

We see that the sign is a triangle and the area of a triangle is given by the expression:

$A=\frac{1}{2}\text{base}\times height$

base=36

height=32

Then,

$\begin{gathered} A=\frac{1}{2}36\times32 \\ A=\frac{1152}{2}=576\text{ square inches} \end{gathered}$
