Question

Find the cost of fencing a vegetable garden of dimensions 2500cm by 18m at the rate of Rs 30 per m.

Answer 1

Answer:

Let the length of the rectangular garden be 4x.

Then breadth=3x.

Area of rectangle=length×breadth

So, area of the rectangular garden=12x

2

Area(given)=1200

⇒12x

2

=1200

⇒x=10

Hence, length=4x=40m

Breadth=3x=30m

Perimeter=2(l+b)=2(40+30)=2×70=140m

Cost of fencing 1m=Rs.7.50

So, cost of fencing 140m=140×7.50=Rs.1050
