Penjelasan dengan langkah-langkah:
Luas:
trapesium=L= 1/2 × jumlah sisi sejajar × tinggi/K = sisi + sisi +sisi
jajargenjang=L= alas × tinggi/K = sisi + sisi + sisi + sisi
belah ketupat=L = 1/2× diagonal pertama × diagonal kedua/K =s + s + s + s
layang layang=L =1/2 × diagonal pertama × diagonal kedua/K = s+s+s+s
segitiga=L =1/2 × alas × tinggi/K =s+s+s+s
