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.
Answer:
approximately 14.2127 but it could also be simplified to the square root of 2 times the square root of 101
If the triangle is increased to twice the base and the height the size will increase by 48 ft²
<h3>How to find the area of a triangle?</h3>
The area of a triangle can be described as follows;
area of a triangle = 1 / 2 bh
where
Therefore, the total area of the garden is 16 square feet.
Hence,
16 ft² = 1 / 2 bh
Hence, if the the triangle is increased to twice the base and the height the size will be as follows;
area = (1 / 2) × 2b × 2h
area = 4 × (1 / 2 bh)
area = 4 × 16
area = 64 ft²
Therefore,
difference in area = 64 ft² - 16 ft²
difference in area = 48 ft²
Therefore, if the the triangle is increased to twice the base and the height the size will increase by 48 ft²
