Question

Find the area of the polygon

Answer 1

Answer:

$687.5 \: {ft}^{2}$

Step-by-step explanation:

Area of polygon = Area of square + Area of triangle

$= {25}^{2} + \frac{1}{2} \times 25 \times (30 - 25) \\ \\ = 625 +\frac{1}{2} \times 25 \times5 \\ \\ = 625 + \frac{1}{2} \times 125 \\ \\ = 625 + 62.5 \\ \\ = 687.5 \: {ft}^{2}$
