Answer 2

Answer:

Given:

• Perimeter of square = 12cm²

Find:

• Area of square?

Solution:

• First we have to have the side of square

• ${ \boxed{ \sf{Perimeter = 4 × S}}}$

$: { \implies{ \sf{12 = 4 \times s}}} \\ \\ : { \implies{ \sf{s = \frac{12}{4} }}} \\ \\ : { \implies{ \sf{s = 3}}}$

So, Side of square is 3

• ${ \boxed {\sf{Area \: of \: square = s²}}}$

$: { \implies{ \sf{Area = 3 \times 3}}} \\ \\ : { \implies{ \sf{Area = 9 {cm}^{2} }}}$

${ \therefore{ \sf{ \pink{Area \: of \: square = 9cm²}}}}$
