Answer:
45 plants
Step-by-step explanation:
Given that:
Length of bed = 120 in
Width of bed = 240 in
Perimeter of a rectangle is given by :
P = 2(length + Width)
Therefore,
P = 2(120 + 240)
Perimeter = 720 inches
If a spacing of 16 inches will be used ; number of plants needed ;
Perimeter / 16
= 720 in / 16 in
= 45
