Cari terlebih dahulu tinggi trapesium:

t² = 26² - ((30-10)/2)²
t² = 676 - 100
t² = 576
t = √576
t = 24 cm

$\: \:$

Menentukan luas

L = ½ × (10 + 30) × 24

L = ½ × 40 × 24

L = 20 × 24

L = 480 cm²

opsi C

___________________________________________

t = √26² - (a - b/2)²

t = √26² - (30 - 10/2)²

t = √26² - (20/2)²

t = √26² - (10)²

t = √26² - 10²

t = √676 - 100

t = √576

t = 24 cm

___________________________________________

L = ½ × (a + b) × t

L = ½ × (30 + 10) × 24

L = ½ × 40 × 24

L = ½ × 960

L = 480 cm²
