Question

A square plot of land has an area of 27.04 square metres . What is the total length of wire needed to fence around the plot using three strands of wire ?

Answer 1

Answer:

$area \: of \: square \: plot \: = 27.04 \\ {side}^{2} = 27.04 \\ side \: = \sqrt{27.04} \\ side \: = 5.2 \: m \\ so \: wire used \: = 3 \times perimeter \: of \: square \\ = 3 \times 4 \times side \\ = 12 \times 5.2 \\ 62.4m$

Answer 2

$\huge\green{A}\red{N}\orange{S}\pink{W}{E}\blue{R}$

Area of square plot= 27.04m²

s²=27.04m²

s=√27.04m²

s= 5.2m

Perimeter of square= 4s

                                 = 4(5.2)

                                 = 20.8m

Three strands of wire

So,

3(20.8)

$\\ \\ =\huge\boxed{62.4m}$
