Question

ement costs about $4.00 per square foot.

Explanation:

Step1: Calculate area of rectangle 1

$\text{Area}_1 = 20 \times 30 = 600$ square feet

Step2: Calculate area of rectangle 2

$\text{Area}_2 = 25 \times 10 = 250$ square feet

Step3: Calculate area of triangle

$\text{Area}_3 = \frac{1}{2} \times 10 \times 10 = 50$ square feet

Step4: Find total area

$\text{Total Area} = 600 + 250 + 50 = 900$ square feet

Step5: Calculate total cost

$\text{Total Cost} = 900 \times 4 = 3600$ dollars

Answer:
