Answer:
$189
Step-by-step explanation:
Price per square feet = $5.25
1. Calculating the fee for the rectangle.
Length 10 feet and width 3 feet
Area= Lents x Width i.e 10X3= 30 feet squared
Charges will be 30 feet squared X$ 5.25= $157.5
2. Calculating fee for the triangle.
Area =(base x height ) divided by 2
i.e 1/2(4feetx3 feet)= 1/2x12
Chargers will be 6 feet squared x 5.25= $ 31.5
3. Total fee =$ 157.5 + $31.5= $189
Customer will pay $ 189 plus taxes
