Question

Prakash has a rectangylar feld whose length and breadth are in the ratio 5:3. He wants to fence the field with barbed wire. If the cost of fencing the field at the rate of ₹15 per metre is ₹9600, find the dimension of the field?

Answer 1

Step-by-step explanation:

Let the length be 5x

Breadth be 3x

Fencing for 1 metre = rupee 15

xm = 9600

x = 9600/15 = 640 m

Perimeter = 2(L+B) = 640

8x = 320

x = 320/8 = 40

Length = 5*40

= 200m

Breadth = 3*40

= 120m

Answer 2

Answer:

Length  = 200m

Breadth = 120m
