Mr . Rajbeer Singh retired from his defense service started a farm nearby the jungle . The overall area of the farm is 216 sq: m . Very often his crops were damaged by wild animals. So he fenced his farm using Tin sheets .
What is the total length of the fencing ? *
(a)20m
(b) 40m
(c) 60m
(d) 80m
Answers
Step-by-step explanation:
The overall area of the farm = 216 sq. m
s2 = 216 sq. m
s = √216 m
= 14.7 m
Total length of the fencing = 4 s
= 4×14.7
= 58.8 m
nearest about 60 m
- 60 m .
Complete Question :- Mr . Rajbeer Singh retired from his defense service started a farm nearby the jungle . The overall area of the farm is 216 sq: m . Very often his crops were damaged by wild animals. So he fenced his farm using Tin sheets .
What is the total length of the fencing if in lengthwise 18m tin sheet is used for the fencing ?
(a) 20m
(b) 40m
(c) 60m
(d) 80m
Formula used :-
- Area of rectangle = Length × Breadth .
- Perimeter of rectangle = 2(Length + Breadth)
Solution :-
Let us assume that, the breadth of the farm is equal to x m .
since, in lengthwise 18m tin sheet is used for the fencing .
So,
→ Length of the farm = 18 m
then,
→ Area of the farm = Length × Breadth = 18 × x = 18x m²
A/q,
→ 18x m² = 216 m²
→ 18x = 216
→ 18x = 18 × 12
dividing both sides by 18,
→ x = 12 m
therefore,
→ Length of farm = 18 m
→ Breadth of farm = 12 m
hence,
→ The total length of the fencing = Perimeter of farm
→ The total length of the fencing = 2(Length + Breadth)
→ The total length of the fencing = 2(18 + 12)
→ The total length of the fencing = 2 × 30
→ The total length of the fencing = 60 m (c) (Ans.)
Hence, The total length of the fencing is equal to (c) 60 m .
