Materi : Perbandingan dan Skala
Luas Trapesium ( Peta )
L = ½ × sisi sejajar × tinggi
L = ½ × ( 15 cm + 12 cm ) × 8 cm
L = 27 cm × 4 cm
L = 80 cm² + 28 cm²
( L = 108 cm² )
Luas Sebenarnya
= 108 cm² × 150
= 16.200 cm²
= 162 dm²
Semoga bisa membantu

Penyelesaian:
a=12cm
b=15cm
t=8cm
s=1:150
----------------------------------------
a=12÷1/150
a=12×150/1
a=1.800cm
a=18m
----------------------------------------
b=15÷1/150
b=15×150/1
b=2.250cm
b=22,5m
----------------------------------------
t=8÷1/150
t=8×150/1
t=1.200cm
t=12m
----------------------------------------
L=½×(a+b)×t
L=½×(18+22,5)×12
L=½×40,5×12
L=40,5×6
L=243m²
----------------------------------------
