Question

The breath of a rectangular farm is 3/5 times it's length.Find the breath if the cost of five layered fencing of wire for the farm is 60000 at the rate of ₹15per meter​

Answer 1

Answer:

Breadth = 150 Meters

Step-by-step explanation:

Rate of fencing wire = Rs 15 Per Meter

Cost of 5 layered fencing = RS 60,000.00

Therefore cost of 1 layer fencing wire = Rs 60,000/5

= Rs 12,000.00

We can assume that one layer of wiring will be equal to the perimeter.

There fore perimeter of the farm = 12,000/15

= 800 Meter

ie 2 (L+B) = 800 -------------------Equation 1

its given that breadth B = 3/5 times of length L

is B = 3/5L ---------------------------Equation 2

Apply above equation 2 in Equation 1

So Equation 2 becomes

2(L + 3L/5) = 800

L + 3L/5 = 400

(5L + 3L)/5 = 400

8L / 5 = 400

8L = 2000

ie L = 2000/8

ie L = 250 Meters

Therefore Breadth = 3/5 x 250

= 750/5 = 150 Meters
