Tolong ya please....

Luas Trapesium = 1/2 x (20+27) x 24
                           = 564 cm²

Luas Segitiga = 1/2 x a x t
                       = 1/2 x 20 x 15 = 150 cm2

Luas bangun tersebut = 564 + 150 = 714 cm²

- B I ( segitiga ) =
( a x t ) : 2 =
= 20 cm x 15 cm =
= 300 cm : 2
= 150 cm²
- B II ( trapesium ) =
( a + b ) x t x 1/2
= ( 27 cm + 20 cm ) x =24 cm x 1/2
= 47 cm x 24 x 1/2
= 564 cm²
Luas = B I + B II = 150 cm² + 564 cm² = B. 714 cm²
Senang bisa membantu >_^
