Find the separate areas.
We have a triangle with base 5 cm and height 5 cm, calculate the area:
Plug in what we know:
Multiply:
Now for the two quarter circles, we know that if we put these two together we will end up with a semi-circle with radius 5 cm. The formula for the area of a circle is:
A semi-circle is half of a whole circle, so the formula for the area of it must be:
Now plug in what we know(use 3.14 to approximate for pi):
Simplify the exponent:
Multiply:
Now add this to the area of the triangle to find the approximate area of the entire figure(round to the nearest tenth):
