Question

A rose garden is formed by joining of a rectangle and a semicircle as shown below. The rectangle is 27 feet long and 19 feet wide. If the Gardner wants to build a fence around the garden how many feet of fence would are required

Answer 1

620.77 feet

Explanation:

We are given that

Length of rectangle,l=27 feet

Width of rectangle,b=19 feet

Diameter of semicircle=d=19 feet

Radius of semicircle,
`r=(d)/(2)=(19)/(2)=9.5 feet`

Fencing would be required for rose garden=l+l+b+
`\pi r`

Where
`\pi=3.14`

Fencing would be required for rose garden=27+27+19+
`9.5* 3.14`

Fencing would be required for rose garden=27+27+19+29.83=620.77 feet

Hence, the fence would be required =620.77 feet
