What is rectangle?
- A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees.
- Hence, it is also called an equiangular quadrilateral.
- Since, the opposite sides are equal and parallel, in rectangle, therefore, it can also be termed as a parallelogram.
Area of Shaded region:
(12+2*7)*20 - 12*20 + 3.14*((12+2*7)/2)² =
14*20 + 530.66 =
810.66 ft²
Therefore, the area of the shaded region = 810.66 ft²
