Question

area of a rectangular garden is 80 sq. metre.its lenght is 10m.find its breadth.if it costs rs.90 per metre to fence the garden,find the total cist of fencing

Answer 1

Area =80
L=10
Ar =l*b
B=80/10=8m
Perimeter =2(l+b)=2(10+8)=2*18=36m
Now cost of fencing =90*36=324rupees

Answer 2

Let breadth be b
Therefore b = 80/10
= 8 meters
Perimeter 2(l + b)
=2(10+8)
=2*18
=36 meters
Cost of fencing
₹(90*36)
=₹324
