Tolong di kerjakan no 6 satu soal aja

L= 1/2 a X t
60 = 1/2 X 8 X t
60 X 2 : 8 = t
15 cm = t(BE) yang A

B. luas ΔADE
L = 1/2 a X t
L= 1/2 X 32 X 15
L=240 cm²

AD , BD=(32 cm-8cm):2
AD , BD=24 cm/2
AD ,BD=12cm

a.t=BE
L=1/2 a×t
60cm²=1/2×8cm×t
t=60cm²/4cm
t=15cm
BE=15 cm

b.ΔADE=ΔBDE-ΔBCE
=1/2×2O CM×15CM-60CM²
=150CM²-60CM²
=90CM²
