Question

the area of a rectangular plot is 340 m2 and its breath is 17 m.find the cost of surrounding the plot with fence at rs 5.70 per metre

Answer 1

Hyee khushi here..
for finding the cost of fence.. we need perimeter..
l*b=340
b=17
l=?
l=340/71
l=20m
2(l+b)=perimeter.
2(20+17)=
2*37=
74=perimeter.
cost of fence.. =area *cost per meter.
=74*5.70
=42.18 rupees.
hope it helps :)

Answer 2

length of the rectangular plot =340 / 17 m =20m

therefore perimeter= 2( 17 + 20)m=›2*37=›74m


in 1 m-rs.5.70
therefore
74m=5.70*74=»421.8rupees....



hope helped...! : )
