The patio at the back of the house is to be extended into the backyard in a semi-circle. What will be the area of the yard
1 answer:
Answer:
A = 413 sq feet
Step-by-step explanation:
The area of the yard = area of rectangle - area of semicircle
The radius of the semicircle, r = 10 feet
The length of the rectangle = 38.5 - 10 = 28.5 feet
So,
The area of the yard = lb - (πr²/2)

So, the required area is equal to 413 sq feet.
