Question 580504
1 square yard = 9 square feet


So 1/9 of a square yard requires four seeds, which means we have the idea that


1/9 sq yd = 4 seeds


Now multiply both sides by 90 to get


90*(1/9) sq yd = 90*4 seeds


90/9 sq yd = 360 seeds


10 sq yd = 360 seeds



So <font color="red">360</font> seeds are needed to plant 10 square yards.
