Answer:
1.) 88cm²
2.) 44.5cm²
3.) 141.37cm²
4.) 44cm²
Step-by-step explanation:
Alrighty, we're just going to do an abridged version, but if you need me to explain it more, I can:
1.) 6 x 8 ÷ 2 = 24
8 x 8 = 64
64 + 24 = 88
1.) 88cm²
2.) 2 + 2 + 3 = 7
7 x 5 ÷ 2 = 17.5
9 x 3 = 27
27 + 17.5 = 44.5
2.) 44.5cm²
3.) 3.14 x 3² = 28.27
3.14 x 6² = 113.1
28.27 + 113.1 = 141.37
3.) 141.37cm²
4.) 3.14 x 4² ÷ 2 = 25.135
4 x 2 = 8
8 x 9 ÷ 2 = 36
8 + 36 = 44
4.) 44cm²
if any of these are wrong, let me know
hope this helps:)
