32. L1 = 1/2 x ( a + b ) x t
= 1/2 x ( 12 cm x 4 cm ) x 10 cm
= 1/2 x 16 cm x 10 cm
= 80 cm²
L2 = 1/2 x a x t
= 1/2 x 12 cm x 34 cm
= 204 cm
L1 + L2 = 80 cm² +204 cm²
= 284 cm²

33. L1 = 22/7 x r x r
= 22/7 x 7 cm x 7 cm
= 154 cm²
L2= s x s
= 7 cm x 7 cm
= 49 cm²
L1 + L2 = 154 cm² + 49 cm²
= 203 cm²

Semoga bisa membantu !!!
