{a) 14m
(b) 12m
(c) 16m
(d) 10m
Answers
Area = 216sq:m
L= 18m
then b = ?
= 216÷18 = 12m
I hope this will help u
- (b) 12 m .
Given :- The overall area of the farm is 216 sq m .
To Find :- What is the breadth of the farm if in lengthwise 18 m tin sheet is used for the fencing ?
{a) 14m
(b) 12m
(c) 16m
(d) 10m
Formula used :-
- Area of rectangle = 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 (Ans.)
Hence, the breadth of the farm is equal to (b) 12 m .
