Question

Jordana is putting a fence around a garden that is shaped like a half circle and a rectangle. A rectangle with length 28 feet and width 14 feet. A semicircle with diameter 14 feet is on top of the rectangle. How much fencing will Jordana need? Use StartFraction 22 over 7 EndFraction for Pi. 64 ft 86 ft 92 ft 114 ft

Answer 1

The answer is C which is 92 ft.

Answer 2

Answer: Jordana will need 92 feet of fencing

Explanation:

Given: Length of rectangle = 28 feet

Width of rectangle = 14 feet

Diameter of semicircle = 14 feet

Therefore radius of semicircle : r =
`(Diamater)/(2) =(AB)/(2) =(14)/(2) =7 \text { feet }`

Now we have to find the perimeter of attached figure for putting fence around a garden

`Perimeter = 2 Length +Width + \text {Circumference of semicircle }\\\\\Rightarrow Perimeter = 2* AD+DC + \pi r\\\\\Rightarrow Perimeter = 2* 28+14 +(22)/(7) * 7 \\\\\Rightarrow Perimeter = 56+14+22 = 92 \text {feet}`

Hence, jordana will need 92 feet of fencing
