Question

length and breadth of a rectangle are 3^1/4 m and 2^3/4 m . what will we the cost of fencing if the rate is rs 2^1/2?​

Answer 1

Step-by-step explanation:

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
