Question

There is a narrow rectangular plot reserved for a school, in a city. The length & breadth of the plot are in the ratio 15:7.at the the rate of Rs. 100per metre it will cost Rs. 44000 to fence the plot. What are the dimensions of the plot

Answer 1

Answer:

Length= 150m

Breadth=70m

Step-by-step explanation:

Let the length be 15x.

And let the breadth be 7x.

Now the perimeter of the plot= 2(l+b)

2(15x+7x)= 44x

Now, as per the question,

Cost of fencing the plot at Rs100 per meter=perimeter x 100= Rs44000

4400x = Rs44000

x = 44000/4400

= 10m

Length =15 x 10=150m

Breadth=7 x 10=70m
