Question

There is a rectangular plot, reserved for the construction of a school . The length and breadth of the plot are in the ratio 8:5 . At the rate of ₹ 100 per metres , it will cost ₹ 52000 to fence the plot . What are the dimensions of the plot ?

​

Answer 1

Answer:

Length is 160m and Breadth is 100m

Step-by-step explanation:

First, we need to find the perimeter of the plot

Total cost of fencing = Rs 52000

Cost per meter = Rs 100

Therefore perimeter of plot

= 52000/100

= 520 m

Let the length and breadth be 8x m and 5x m respectively

2 ( 8x + 5x ) = 520

2 × 13x = 520

26x = 520

x = 520/26 = 20

Length = 8x = 8 × 20 = 160 m

Breadth = 5x = 5 × 20 = 100m
