Question

the area of a rectangular field is 78 sq m. its length is 13m. find its breadth. if the cost of fencing is rs 55 per m how much would cost to fence the entire field for grade 6th

Answer 1

Let the breadth be B

ATQ
13×B = 78
13B=78
B=6.5

Perimeter = 2 (13+6.5)
= 2×19.5
= 114

Therefore cost of fencing the entire field =Rs. (114×55)
=Rs.6270

Answer 2

Area of rectangle = length × breadth
78 = 13 × breadth
breadth = 6 m.

Perimeter = 2(l+b)
= 2(13 + 6)
= 38m.
Cost of rectangular field = 38 × 55
= rupees 2090.
