Respuesta :

Given an irregular figure.

The figure consists of a right triangle and a semi-circle

The triangle has a base = b = 12 ft

And a height = h = 6 ft

Area of the triangle =

[tex]\frac{1}{2}bh=\frac{1}{2}\cdot12\cdot6=36ft^2[/tex]

The semi-circle has a radius = r = 6 ft

The area of the semi-circle =

[tex]\frac{1}{2}\cdot\pi\cdot r^2=\frac{1}{2}\cdot3.14\cdot6^2=\frac{1}{2}\cdot3.14\cdot36=56.52ft^2[/tex]

So, the total area =

[tex]36+56.52=92.52[/tex]

Rounding to the nearest tenth

So, the answer will be area = 92.5 ft^2
