Answers
Step-by-step explanation:
Given :-
A lawn is rectangular in shape and measures 36m by 27m.One bag of fertilizer covers 360sq.m.
To find :-
How many full bags must be purchased for the whole lawn?
Solution :-
Given that
The measurements of a rectangular lawn are
36 m and 27 m
Let the length be 36 m
Let the breadth be 27 m
We know that
Area of a rectangle = lb sq.units
Area of the rectangular lawn = 36×27 sq.m
=>972 sq.m
Area is 972 sq.m
Area coverd by a bag of fertilizer = 360 sq.m
Let the number of bags required to cover the lawn be n
Total area covered by such n covers
=> n × 360
=> 360n sq.m
According to the given problem
=> 360n = 972
=> n = 972/360
=> n = 2.7
number of bags should be a natural number.
The nearest whole number to 2.7 is 3
So, We need 3 bags
Answer:-
The required number of fertilizer bags for covering whole lawn is 3
Used formulae:-
→ Area of a rectangle = lb sq.units
- l = length
- b = breadth
