Bed 10

A bed in the shape of two equilateral triangles sharing a common side, with a side length of 2.5 m, is to be planted with seedlings of an ornamental shrub. The gardener recommended leaving 40 cm between individual seedlings and 10 cm from the perimeter edge for the outermost seedlings. Determine the maximum number of seedlings needed to plant this bed.

Final Answer:

n =  30

Step-by-step explanation:

a=2.5 m cm=2.5 100  cm=250 cm m=40 cm s=10 cm  a2=a2 s=2502 10=230 cm r1=a2/m=230/40=5  n1=r12=52=25  m2=m2(m/2)2=402(40/2)2=20 3 cm34.641 cm r2=a2/m2=230/34.641=6  n2=r2 r1=6 5=30  n=n2=30
