Question

The area of a square plot of land is 328 square metre. find the length of one side of the plot correct to 1 decimal place.

Answer 1

Answer:

$\red { side \: of \: square \:plot} \green {≈18.1\:m}$

Step-by-step explanation:

$Let \: side \: of \: square \:plot = a \:m$

$Area \: of \: the \: plot = 328 \:m^{2}$

$\implies a^{2} = 328 \:m^{2}$

$\implies a = \sqrt{328}$

$\implies a = 18.11 \:m$

$\implies a ≈ 18.1 \:m \\ (Corrected \: to \: 1 \:decimal \: place )$

Therefore.,

$\red { side \: of \: square \:plot} \green {≈18.1\:m}$

Answer 2

Answer:

Step-by-step explanation:

Let \: side \: of \: square \:plot = a \:mLetsideofsquareplot=am

Area \: of \: the \: plot = 328 \:m^{2}Areaoftheplot=328m

2

\implies a^{2} = 328 \:m^{2}⟹a

2

=328m

2

\implies a = \sqrt{328}⟹a=

328

\implies a = 18.11 \:m⟹a=18.11m

\begin{gathered} \implies a ≈ 18.1 \:m \\ (Corrected \: to \: 1 \:decimal \: place )\end{gathered}

⟹a≈18.1m

(Correctedto1decimalplace)

Therefore.,

\red { side \: of \: square \:plot} \green {≈18.1\:m}sideofsquareplot≈18.1m
