Certainly! Let's find the square of each given number step by step. Squaring a number means multiplying the number by itself:

### (a) 20
To find the square of 20:
[tex]\[ 20 \times 20 = 400 \][/tex]

So, the square of 20 is 400.

### (b) 10
To find the square of 10:
[tex]\[ 10 \times 10 = 100 \][/tex]

So, the square of 10 is 100.

### (c) 30

[tex]\[ 30 \times 30 = 900 \][/tex]

So, the square of 30 is 900.

### (d) 50
