tolong dijawab ya TT

sisi tegak
t²= 15²-12²
t² = 225 -144
t²= 81
t=√81
t = 9

perbandingan = 2:3
trapesium atas
=18-9
=9

Ltrapesium1
=½ × (jmlsisi sejajar) × t
=½ × (18+9)×12
=½ × 27 ×12
=27 × 6
=162m²

trapesium2
t = 2/3 × 12
t= 8m
sisiatas
=2/3 × 9
=6m
Ltrapesium 2
=½ × (jmlsisi sejajar)×t
=½ × (12+6) × 8
=18 × 4
=72m²

luas tanah
=162-72
=90m²

btw itu soal simulasi gladi bersih yaa
