diketahui :

- bangun = trapesium

- luas = 98 cm²

- b = 10 cm

- a = 18 cm

ditanya :

tinggi trapesium

jawab :

Luas = ½ × ( a + b ) × t

98 = ½ × ( 10 + 18 ) × t

98 = ½ × 28 × t

t = 98 : 14

t = 7 cm

kesimpulan :

jadi tinggi trapesium tersebut adalah 7 cm

Penyelesaian

$Luas = \frac{1}{2} × ( a + b ) × t \\ \\ 98 = \frac{1}{2} × ( 10 + 18 ) × t \ \\ \ 98 = \frac{1}{2} ×( 28 × t) \\ \\ t = \frac{98}{14} \\ \\ t = 7 cm$
