Grandfather 3

Grandfather bought a square field of 900 square metres. A beet seedling occupies 20 square centimetres, and a parsley seedling occupies 10 square centimetres. He started by planting beets in the first row, with every second row planted with parsley. He alternated the rows. How many beet and parsley seedlings did he plant, given that he always left a 20-centimetre-wide path between rows of beets and parsley?

Final Answer:

r =  50000
p =  50000

Step-by-step explanation:

S=900 m2 a=S=900=30 m  20 cm2 = 5 4 10 cm2= 5 2  r2=0.05+0.05+0.20=0.3 m s=0.04+0.02=0.06 m  n=a/r2=30/103=30:103=30 310=330 10=3300=100  r=n sa=100 50330=50000
p=n sa=100 50330=50000
