Explanation:

Step1: Identify base and height

The base $b = 11$ pies and height $h=4$ pies.

Step2: Apply area formula

Use the formula $A=\frac{1}{2}bh$. Substitute $b = 11$ and $h = 4$ into the formula: $A=\frac{1}{2}\times11\times4$.
First, calculate $11\times4 = 44$, then $\frac{1}{2}\times44=22$.

Answer:

22 square - pies
