Question

This is my last question to master my topic PLEASE ANSWER ASAP AND CORRECTLY ! i would add more points for this problem but people tend to just comment to get the better points, ill rate you as the highest though please!!!

Answer 1

Area formula of a rectangle
A = length x width
Area formula of a semi-circle
A =
`(1)/(2)`
`\pi`r²
Since there are two semi-circles, if you join them together you will get a circle
Area formula of a circle
A =
`\pi`r²

To find the total area, you should add the area of the rectangle with the area of the circle
The given are
Length = 84 m
Width = 66
Radius = 33 (the diameter of the circle is 66, the radius is half the diameter)
A of rectangle = 84 x 66 = 5544 m²
A of circle =
`\pi`(33)² = 3.14 (1089) = 3419.46 m²
Total Area = 5544 + 3419.46 = 8963.46 m²
Your answer will be 8963.46 m²
