Answer:

26.13 ft²

Explanation:

The total area is twice the area of the right triangles plus half the area of a circle of radius 3 ft.

Semicircle area = (1/2)(πr²)

semicircle area = (1/2)(3.14)(3 ft)² = 14.13 ft²

The area of the two right triangles is ...

total triangular area = (3 ft)(4 ft) = 12 ft²

Then the area of the figure is ...

figure area = semicircle area + total triangular area

= 14.13 ft² + 12 ft² = 26.13 ft²
