3. The length and breadth of a rectangular field are in
the ratio 3:2 if the area of the field is 3456 m². Find
the cost of fencing the field at Rs. 2.50 per meter.
(a) Rs. 600 (b) Rs. 500
(c) Rs. 400 (d) Rs. 300​

Answer 1

Length and Breath are in Ratio 3:2

Assume Length be 3x Also Breath be 2x

Then Area= L*B

3456= 3x × 2x

Then 6x^2 = 3456

x^2=576

Then X = 24

Value of x Always Positive

Then L = 72 Also B = 48

So Perimeter = 2(72+48)

2(120)

240m......

So Cost of Fencing= 240×2.50

So The Cost of Fencing is 600...............

A
