tolong di bantu dong soal no. 4 & no.5

luas trapesium = 1/2 × jumlah sisi sejajar × tinggi
L = 1/2 × (15 + 30) × 20
L = 1/2 × 45 × 20
L = 450 cm^2
jawabannya c
mohon maaf jika kurang benar

4. L = (a+b) × T ÷ 2

= (15+30) × 20 ÷ 2

= 45 × 20 ÷ 2

= 45 × 10

= 450 (C)


5. D1 = 15 + 7

= 22 cm

D2 = 5 + 5

= 10 cm

L = D1 × D2 ÷ 2

= 22 × 10 ÷ 2

= 22 × 5

= 110 cm^2 (A)
