Find the area and perimeter of the following figure

143.79

Step-by-step explanation:

The area of the figure can be found by splitting it into two shapes - a semi circle and a trapezoid.

The area of a semi-circle is found using A = 1/2πr² where r = 4.5 since the diameter is 9. A = 1/2π(4.5)² = 31.79.

The area of the trapezoid is found using A = 1/2(a+b)h = 1/2(23 + 9)(7) = 112.

Together the area is 31.79 + 112 = 143.79.

answer: 1 + 1 = 11
