Answer:

Option (4)

Step-by-step explanation:

From the picture attached,

ΔABC is a right triangle.

Since, inscribed angle in a semicircle is always a right angle, Hypotenuse AC will be the diameter of the circle.

Length of diameter AC = 58 ft

Radius of the circle = [tex]\frac{58}{2}=29[/tex] ft

Area of the circular garden = πr² [r = radius of the circle]

                                             = π(29)²

                                             = 2642.08 ft²

Area of the right triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                          = [tex]\frac{1}{2}(27)(50)[/tex]

                                          = 675 ft²

Area of the of the region covered with grass = Area of the circular garden - Area of the right triangle

= 2642.08 - 675

= 1967.08 ft²

≈ 1966 [Nearest value]

Option (4) will be the answer.
