Question

The breadth of a rectangle field is 20 metre less than its length. If its length is 80 metre, find the cost of fencing the field at the rate of ₹ 3.50 per meter.

Answer 1

Answer:

Step-by-step explanation:

length=80

breadth=80-20=60

Perimeter=2(l+b)

2 (80+60)

140×2

280m

280×3.50

980 rupees

Answer 2

Length = 80m
therefore,breath = 80 - 20
=60 m
$2(l \: + \: b)$
2(80 + 60) = 280m

cost of fencing per meter = rs.3.50
therefore,

280 × 3.50
= Rs.980
