Let's solve the exercises step by step.

Exercise 1: Calculate the squares
We need to compute the square of each number (i.e., multiply the number by itself).
a) $ 2^2 = 2 \times 2 = 4 $
b) $ 7^2 = 7 \times 7 = 49 $
c) $ 4^2 = 4 \times 4 = 16 $
d) $ 10^2 = 10 \times 10 = 100 $
e) $ 6^2 = 6 \times 6 = 36 $
f) $ 3^2 = 3 \times 3 = 9 $
g) $ 8^2 = 8 \times 8 = 64 $
h) $ 1^2 = 1 \times 1 = 1 $
i) $ 5^2 = 5 \times 5 = 25 $
j) $ 11^2 = 11 \times 11 = 121 $
k) $ 2^2 = 2 \times 2 = 4 $ (same as a)
l) $ 9^2 = 9 \times 9 = 81 $

Exercise 2: Match each squared number to its correct answer
We are given a list of squared numbers on the left and possible answers on the right. We need to match them correctly.
Given:
Left side:
- $ 11^2 $
- $ 8^2 $
- $ 6^2 $
- $ 5^2 $
- $ 2^2 $
- $ 10^2 $
- $ 7^2 $
- $ 3^2 $
- $ 4^2 $
- $ 9^2 $
- $ 12^2 $
- $ 1^2 $
Right side (answers):
- 36
- 4
- 121
- 16
- 64
- 49
- 81
- 144
- 1
- 9
- 100
- 25
Now, let’s compute or recall each square and match:
- $ 11^2 = 121 $ → already matched to 121
✔
- $ 8^2 = 64 $ → matches with 64
- $ 6^2 = 36 $ → matches with 36
- $ 5^2 = 25 $ → matches with 25
- $ 2^2 = 4 $ → matches with 4
- $ 10^2 = 100 $ → matches with 100
- $ 7^2 = 49 $ → matches with 49
- $ 3^2 = 9 $ → matches with 9
- $ 4^2 = 16 $ → matches with 16
- $ 9^2 = 81 $ → matches with 81
- $ 12^2 = 144 $ → matches with 144
- $ 1^2 = 1 $ → matches with 1
---
Final Matching (Exercise 2):
Draw lines from left to right:
- $ 11^2 $ → 121
✔ (already done)
- $ 8^2 $ → 64
- $ 6^2 $ → 36
- $ 5^2 $ → 25
- $ 2^2 $ → 4
- $ 10^2 $ → 100
- $ 7^2 $ → 49
- $ 3^2 $ → 9
- $ 4^2 $ → 16
- $ 9^2 $ → 81
- $ 12^2 $ → 144
- $ 1^2 $ → 1
