Question

the area of a square piece of land is 6400sq m.let's find the cost of fencing all around the land at rs. 3.50 per meter.​

Answer 1

Answer:

Step-by-step explanation: Area of the square land = 6400 sq m.

                                             Side of the square land = √6400 = 80 m

Distance needed for fencing the land = Perimeter of the land - 4 x 80 = 320 m

∴Cost of fencing the land at ₹3.50 per m = 320 x ₹3.50 = ₹1120

Answer 2

Answer:

Rs 1120

Given:

Area of square piece of land=6400 m^2

Cost of fencing land at Rs 3.50 per meter

To find:

Cost of fencing all around the land

Solution:-

we know that

Area of square=(side)^2

Area of sqaure=6400

${(side)}^{2} = 6400$

$side = \sqrt{6400}$

$side = 80$

Now

Perimeter=4 × side

=4 × 80

=320

Cost of fencing=320 × 3.50

= Rs 1120

Therefore;

Cost of fencing all around the land is Rs 1120
