Tolong jawabkan yaaaa dengan cara kerjax

HI = eh 2 -ei2
10^2-6^2=100-36=64=8
Dk= Hidup+2+2=8+4=12 m
EF/AB=HG/DC=HI/DK
EF/Ab=HI/DK=24/AB=8/12=24/AB=2/3 2AB=3*24
Ab=3*24/2=36 m
HG/DC=HI/DK=12/DC=8/12=12/DC=2/3=2DC=3*12=DC=3*6=18 m
Luas jalan=luas tanah - luas kolam
= Labcd-lefgh
=1/2*DK*(AB+DC)-1/2*HI*( EF+HG)
=1/2*2*(36+18)-1/2*8*(24+12)
=6*54-4*36
=324-144
=180(C)
