Question

the length and the breadth of a rectangular field are in the ratio 5 is to 4 and its area is 3318 square find the cost of Finance it ₹ 75 per metre​

Answer 1

Answer:

Length = 64.5 m , Breadth = 51.6 m , Cost of fencing = Rs 248850

Step-by-step explanation:

We Have :-

Area of Rectangular Plot = 3318 m²

Ratio of Length and Breadth = 5:4

Cost of fencing = Rs 75

To Find :-

Length , Breadth and Total Cost of Fencing

Formula Used :-

Area of Rectangle = Length * Breadth

Solution :-

Let the

Length be 5x

Breadth be 4x

Area = Length * Breadth

3318 = 5x * 4x

3318 = 20x²

x² = 165.9

x = 12.9 m

Length = 5x = 64.5 m

Breadth = 4x = 51.6 m

Cost of fencing

1 m² = Rs 75

3318 m² = Rs 75 * 3318

= Rs 248850

Length = 64.5 m , Breadth = 51.6 m , Cost of fencing = Rs 248850
