Answer» 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!!!!

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!!!!
