Answer:

1. A = s × s or A = s²

= 8 × 8

= 64 cm²

2. A = l × w

sorry I didn't know what's the width so I can't solve it

3. A = s × s

= 30 × 30

= 900 m²

4. A = ½ bh

There is no base in the sentence

5. A=bh

= 200 × 12

= 2,400

6. A = ½ ( base1 × base2 ) × height

There is no bases

7. A=πr2

= 3.14 × 28 × 28

= 3.14 × 784

= 2,461.76 cm²

8. A=πab

= 3.14 × 10 × 12

= 3.14 × 120

= 376.8 cm²

9. A = r². a /2

=14² × 100/2

= 196 × 50

= 9,800

10. A = s × s

= 23 × 23

= 529 m²

Step-by-step explanation:

You didn't complete the other numbers that's why I can't solve it but you can atleast try your best to solve it
