Bed 10

A bed shaped like two equilateral triangles with 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 the individual seedlings and 10 cm of the perimeter for the seedling itself. Determine the maximum number of seedlings needed to plant this bed.

Correct 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
