Free Garden Catalogs

Can anyone help me with this math problem please?

Mr. Petri has a rectangular plot of land with length=20 ft and width=10 ft. He wants to design a flower garden in the shape of a circle with two semicircles at each end of the center circle. He will fill in the remaining area with wood chips. If one bag covers 5 square ft, how many bags must he buy? Mr. Petri has a rectangular plot of land with length=20 ft and width=10 ft.

1. N = (20*30 - 50π)(1 bag/5 ft^2) N ≈ 88.584 bags ≈ 89 bags
