Question

find the area of ractangular if it's perimeter is 500 m and breadth is 120 m ,also find the cost of grassing on it at the of rs3.80 per m2​

Answer 1

Answer:

Area = 15600m/sq.

Step-by-step explanation:

perimeter=2 (l+b)

2 (l+120)=500

l+120=250

l=130

area=l×b

130×120=15600m/sq.

Answer 2

perimeter=500m, breadth=120m

perimeter=1/2(length+breadth)

500 =1/2(l+120)

120×2=l+120

240-

120=l

120m=l

area of rectangular=l×b

=120×120

=14400msquare

cost of one square metre=3.80rupees

cost of 14400square metre =14400×3.80

=rs54720
