Question

The area of a square plot is 100 sq. m. then the cost of fencing around the plot at Rs. 15/- per meter is Rs. __ /-​

Answer 1

Step-by-step explanation:

∵ Perimeter of square field = 4 x its side = 4 x 55 m

∴ Length of required fencing = 220 m Now, the cost of fencing = its length x its rate

= 220 m x Rs. 32 per metre

= Rs. 7040

Answer 2

Step-by-step explanation:

Here,

Area of the square plot = 100m²

therefore,

let the side of the square be X meter.

now,

${x}^{2} = 100$

$= x = 10 \: m$

then,

$perimeter \: = 4 \times x$

$= 4 \times 10$

$= 40 \: m$

so,

cost of fencing = RS 15/- meter

again,

$total \: cost \: to \: fencing \: the \: square \: plot$

$= 15 \times 40$

$= 600 \: rupees$

this is the required answer..

thanks a lot..
