The first question requires the area of the circle with a radius of 5 meters
Area formula of a circle is; A = [tex] \pi [/tex]r² = [tex] \pi [/tex](5)² = 25[tex] \pi [/tex] square meters
So your answer will be Option B
The second question asks us to find the area of the remaining rectangle
We have a rectangle with given length to be 10 in and width of 6 in The Area formula of a rectangle is: A = length x width = 10 x 6 = 60 in²
We have a triangle within the rectangle with a base of 1.5 in { 10 - 8.5 } and a height of 1.5 in { 6 - 4.5 } The Area formula of a triangle is: A = [tex] \frac{1}{2} [/tex] x base x height =[tex] \frac{1}{2} [/tex] x 1.5 x 1.5 = 1.125 in²
For finding the remaining area of the rectangle after removing the triangle, we need to subtract the area of the triangle from the area of the rectangle
Remaining area = Area of rectangle - Area of triangle = 60 - 1.125 = 58.875 in²
