Larsir = Lbsr - Lkecil

Lbsr
= (d1 x d2)/2
= ( (6 + 4 + 4 + 6) x (5 + 5)) /2
= (20 x 10)/2
= 100 cm2

Lkcil
= (d1 x d2)/2
= (4 + 4) x (5 + 5) /2
= 8x10/2
= 40 cm2

100-40 = 60 cm2

Larsiran = luas seluruh - luas tidak diarsir

L seluruh= 1/2×d1×d2
1/2×2(6+4)×2(5)
1/2×20×10
100 cm²

Luas tidak diarsir
1/2×d1×d2
1/2×2(4)×2(5)
1/2×8×10
=40 cm²

L arsiran = 100-40 = 60 cm²
