Question

The area of a rectangular plot is 330 sq m and its breadth is 15 m. Find. The length of the plot and the cost of fencing it at rate of rupees 8.50 per metres

Answer 1

Answer: The length of the plot is 22 m and the cost of fencing it would be Rs 629.

Step-by-step explanation:

Given that,

The area of rectangular plot= 330 m^2

Breadth=15 m

Let x be the length of the rectangular plot and y be the breadth.

Area=330

xy= 330

15x=330    (because y=15)

x=22

So,

Length= 22 m

We want to find the cost of fencing, so first find perimeter of the rectangular plot as follow:

Perimeter= 2(x+y)= 2( 22+15)=2*37=74 m

Now,

The cost of fencing per meter= Rs 8.50

So,

The cost of 74 m of fencing= 8.50*74= 629
