Answer:
36cm
Step-by-step explanation:
There are two ways of solving this problem.
1) Individually calculating all the sides of the square.
=>9+9+9+9=36cm
or
2) Multiplying the side with 4
=>4a= 4 × 9 =36 cm.
either way it is fundamentally same as multiplication is just a repeated addition. And it is way more direct and easier the second way. I suggest you to follow the second method.
