Luas

= 1/2 × ( 28 cm + 20 cm ) × 10 cm + 1/2 × 3,14 × 10 cm × 10 cm

= 240 cm2 + 157 cm2

= 397 cm2

Option = A

L.1/2 lingkaran = 1/2 x π x r²
=1/2 x 3,14 x 10²
= 1/2 x 3,14 x 100
= 1/2 x 314
= 157 cm²

L.trapesium = 1/2 x (a + b) x t
= 1/2 x (20+28) x 10
= 1/2 x 48 x 10
= 24 x 10
= 240 cm²

L.gabungan = 157 + 240 = 397 cm² (A.)

SEMOGA MEMBANTU YAA….
