Answer 1

Answer:

• Area of section is 981 square feet

Step-by-step explanation:

Given trapezoid with:

• Bases 57 feet and 52 feet;
• Height 18 feet.

To find

• Area of trapezoid

Solution

Equation of area:

• A = (b₁ + b₂)h/2

Substitute values and calculate:

• A = (57 + 52)*18/2 = 109*9 = 981 ft²
