Answer:
≈ 743 m²
Step-by-step explanation:
The figure is composed of a triangle and a semi- circle.
area of triangle = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
here b = 30 and h = 26, thus
A = [tex]\frac{1}{2}[/tex] × 30 × 26 = 15 × 26 = 390 m²
------------------------------------------------------
area of semi- circle = [tex]\frac{1}{2}[/tex]πr² ← r is the radius
Here diameter = 30, thus r = 30 ÷ 2 = 15, thus
A = 0.5 × 3.14 × 15² = 1.57 × 225 = 353.25 m²
Total area = 390 + 353.25 = 743.25 ≈ 743 m²
