Answer: A = 198.6cm²

Step-by-step explanation: The figure includes two semi circles on both ends. These can be solved as a whole circle with a diameter of 10cm because each semi circle is 5cm.

r = 10/2= 5cm

Area of circle:

A = πr²

A = 3.142*5²

A = 3.142*25

A = 78.55

A = 78.6cm²

The remaining section of the shape is a rectangle with a length of 12cm.

To get this, you subtract 10 from 22 because each semi circle is 5cm which adds up to 10cm.

The rectangle has a width of 10cm.

Area of rectangle:

A = lw

A = 12*10 = 120cm²

The total area of the shape:

A = 120 + 78.6

A = 198.6cm²
