tinggi = 5/6/8/9
Rumus = Luas= 1/2x(Sisi Sejajar1 +sisi sejajar2)x tinggi
Jika tinggi=5=1/2x40x 5 = 100cm²
Jika Tinggi=6=1/2x40x6 = 120cm²
Jika Tinggi=6=1/2x40x8=160cm²
Jika Tinggi=9=1/2x40x9=180cm²
2.Soal Burem
3.Luas Trapesium = 1/2x(s1+s2)xtinggi
45m²=1/2 x (10m + y)x5m
90m²=(10m + y)x 5m
18m²=10m + y
y= 8m
4.Diketahui = Diagonal 1 =500cm
Luas = 2000cm²
Luas Layang² = diagonal1 x diagonal 2 x 1/2
2000cm² = 500cm x d2 x 1/2
2000cm² x 2 = 500cm x d2
4000cm² = 500cm x d2
d2= 8cm
5.Luas layang2 = d1xd2x1/2
=25cm x 3? x 1/2
