Verified answer

Penyelesaian :
Nomor 26
Luas persegi panjang
= p × l
= 25 cm × 18 cm
= 450 cm^2

Luas trapesium
= 1/2 × ( a + b ) × t
= 1/2 × ( 25 cm + 35 cm ) × ( 30 - 18 )
= 1/2 × 60 cm × 12 cm
= 360 cm^2

Luas gabungan
= 450 cm^2 + 360 cm^2
= 810 cm^2
Opsi > C

Nomor 30
Volume tabung
= phi × r^2 × t
= 22/7 × 7 cm × 7 cm × 10 cm
= 1540 cm^3
Opsi => A

Good Luck :)
