rectangular field is 3:2 and its area is 11094
sq m. What will be the cost of fencing the
field at the rate of 2.50 per metre?​

Answer 1

Answer:

1075 rupees

Step-by-step explanation:

Given that the length and breadth of a rectangular field are in the ration 3:2 and its area is 11094.

Let us take the legth and breadth as 3x and 2x.

Area of a rectangle = l × b

11094 = 3x × 2x

11094 = 6x²

x² = 1849

x = √1849

x = 43

Length = 3x = 3(43) = 129 m

Breadth = 2x = 2(43) = 86 m

Perimeter of a rectangle = 2(l + b)

= 2(129 + 86)

= 2(215)

= 430 m

Rate of fencing per meter = 2.5 Rs

Rate of fencing 430 m = 2.5 × 430 = Rs. 1075

Hope this helps you!!!!
