Answer:
159.25cm²
Step-by-step explanation:
A=lw
A=12×10cm
The rectangle’s area is 120cm²
First, substitute the given information into the equation for the area of a circle.
A=πr²
A=(3.14)(5²)
A=3.14×25
A=78.5
Next, because the figure is only half of a circle, divide this in two.
78.5/2= 39.25cm²
Asc=39.25cm²
Add the two areas together.
A=Ar+Asc
120cm²+39.25cm²
The area of the combined figure is 159.25cm²
