A rose garden is formed by joining a rectangel and a semicircle. The rectangle is 35 ft long and 35 ft wide. if the gardner wants to build a fence around the gardner, how many feet of fence are required?

Three sides of the rectangle (a square) will be fenced  = 3*35  =  105ft

 

The semi-circle will have a radius of   (35/2)  =17.5 ft

And the additional fencing required = (1/2) the perimeter of the circle  = pi (17.5)  = 17.5 pi ft

 

So.....the total fencing required =  105 + 17.5 pi ≈  160 ft
