luas trapesium.luas 300 cm² sisi a 18 cm sisi b 22 cm.ditanya tinggi?

Luas = 300 cm²
a = 18 cm
b = 22 cm

Luas = 1/2 x (a + b) x t
300 = 1/2 x (18 + 22) x t
300 = 1/2 x 40 x t
300 = 20 x t
t = 300 / 20
t = 15 cm

L = 300cm²
a = 18cm
b = 22cm
t ...?

L = (a+b)×t/2
300 = (18+22)×t/2
600 = 40t
15cm = t
