Answer:
10
Step-by-step explanation:
first we need to find the area of the garden, or how much space we need to cover.
A = length * width, so 12 * 5 = 60
if one bag covers 6 yards, then 60 / 6 = 10
Charles need to buy 6 bags of fertilizer to cover the entire garden.
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
The area can be defined as the space occupied by a flat shape or the surface of an object.
Area = length × breadth
According t o the given question.
Length of the rectangular garden = 5yds
Width of the rectangular garden = 12 yds
Also, One bag of fertilizer can cover 6yds
Area of rectangular garden = 5 × 12 = 60 square yds
Therefore,
The number of bags of fertilizer required to cover 60 yards = [tex]\frac{60}{6} = 6[/tex]
Hence, Charles need to buy 6 bags of fertilizer to cover the entire garden.
