Answer:
61
Step-by-step explanation:
Rectangle area=
[tex]60 \times 40 = 2400yd ^{2} [/tex]
The area at the right
[tex](\pi \times 20^{2} ) \div 2 = 628yd^{2}[/tex]
Total area = 2400+628=3028yd^2
Now you have to find the quantity of grass seed needed (1pound for every 50yd square)
3028/50=60.56 (which is almost 61)
