Question

The breadth of a rectangular field is twice its length . If the area of the field is 1058m,find the cost of fencing it at rupees 35 per m​

Answer 1

Answer:

Step-by-step explanation:

Let Length = x

Breadth = 2x

Answer 2

Answer: Rs. 4830..

Step-by-step explanation:

[ Note: Used sign * for multiplication.]

Let B  be breadth of a rectangular field and L be  length.

B=Twice of Length= 2 * L

Here.

Area of Rectangle = length * Breadth = L* B = 1058.

=> L * (2* L)=1058 sqm...

=> 2 (L * L)=1058...

=Square of L = 1058/2=529...

=> L = Length =Square root of 529=23 m...

Breadth= 2x L = 2 * 23= 46 m

So we get Length L= 23 m and Breadth B=46...

Length of Fence= Perimeter of Rectangle= 2(l+b) = 2 * (23+46) = 2 * 69 =138 M.

So Length of Fence= 138 Meter.

Here given Rate of Fence = 138 per meter.

So Total cost = rate cost/meter * total length meters =138 * 35 ....

So Total cost of Fence for one round surrounding = Rs. 4830..
