Answer 2

Given:

• perimeter of an square is 15 cm.

To Find:

• it's area.?

Solution:

$\sf {\purple {\underline{ \leadsto \: to \: find \: the \: area \: we \: must \: know \: the \: value \: of \: side}}}$

__________________________________________

$\sf: \implies perimeter = 4 \times side \\ \\ \sf: \implies 15cm = 4 \times side \: \: \: \: \: \: \: \\ \\ \sf: \implies \: side = \frac{15}{4} cm \: \: \: \: \: \: \: \: \: \: \:$

$\sf {\red{ \underbrace{area \: of \: a \: square = side \times side}}}$

__________________________________________

$\sf \: : \implies area = \frac{15}{4} \times \frac{15}{4} \\ \\ \sf \: : \implies area = \frac{225}{8} \: \: \: \: \: \: \: \: \: \\ \\ \sf \: : \implies area = 28\frac{1}{8} cm$

$\blue{ \underline{ \boxed{ \pink{ \mathfrak{ \therefore \: area \: of \: the \: square = 28 \frac{1}{8} cm}}}}}$
