Question

The area of a square plot is 5625 metre square . find the length of the wire that can go five times along the boundary of the plot

Answer 1

Answer:

area = side^2

so side=sqrt(5625)=75

the perimeter of the plot is 4*75=300

we need to go around 5 times ,so 5*300=1500

therefore,the length of the required wire is 1500m

Answer 2

$\:\:$

$\green{\underline \bold{Given :}}$

$\:\:$

• Area of a square plot is 5625 sq. m

$\:\:$

$\red{\underline \bold{To \: Find:}}$

$\:\:$

• Length of the wire that can go 5 times along the boundary of the plot

$\:\:$

$\large{\orange{\underline{\tt{Solution :-}}}}$

$\:\:$

$\underline{\bold{\texttt{We know that,}}}$

$\:\:$

$\purple{\bold{Area \: of \: square :}}$

$\:\:$

$\bf \dashrightarrow side \times side$

$\:\:$

$\purple{\underline \bold{According \: to \: the \ question :}}$

$\:\:$

Area is 5625 sq. m

$\:\:$

So,

$\:\:$

$\sf \longmapsto side^2 = 5625$

$\:\:$

$\sf \longmapsto side = \sqrt { 5625 }$

$\:\:$

$\bf \implies side = 75 \: m$

$\:\:$

$\purple{\bold{Perimeter \: of \: square :}}$

$\:\:$

$\bf \dashrightarrow 4 \times side$

$\:\:$

We need the length of the wire that can go five times along the boundary of the plot.

$\:\:$

So,

$\:\:$

$\underline{\bold{\texttt{Length of wire will be }}}$

$\:\:$

$\sf \longmapsto 5(4 \times side )$

$\:\:$

$\sf \longmapsto 5(4 \times 75 )$

$\:\:$

$\sf \longmapsto 5 (300)$

$\:\:$

$\bf \dashrightarrow 1500 \: m$

$\:\:$

Hence length of wire needed will be 1500 m
