Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ \: 81 \: {cm}^{2} }}}}}[/tex]
Step-by-step explanation:
Given , length of a square = 9 cm
We know that, all the sides of the square are same.
Finding the area of the square
[tex] \boxed{ \sf{area \: of \: a \: square = {l}^{2} }}[/tex]
[tex] \dashrightarrow{ \sf{ \: area \: of \: a \: square \: = \: {(9 \: cm)}^{2} }}[/tex]
[tex] \dashrightarrow{ \sf{area \: of \: a \: square \: = 9 \: cm \: \times \: 9 \: cm}}[/tex]
[tex] \dashrightarrow{ \sf{area \: of \: a \: square = 81 \: {cm}^{2} }}[/tex]
Hope I helped!
Best regards! :D
