AB / AE = AD / AG
12 cm / 12 cm + BE = 8 cm / 16 cm
12 cm x 16 cm = 8 cm ( 12 cm + BE )
192 = 96 + 8BE
8BE = 192 - 96
8BE = 96
BE = 96/8
BE = 12 cm
AD / AG = DC / GF
8 cm / 16 cm = 6 cm / GF
GF = 16 cm x 6 cm : 8 cm
GF = 12 cm
Luas Trapesium
= 1/2 x t x Jumlah sisi sejajar
= 1/2 x AG x ( AE + GF )
= 1/2 x 16 cm x ( 12 cm + 12 cm + 12 cm )
= 8 cm x 36 cm
= 288 cm ²
