Luas persegi panjang
L = p x l
L = 37 x 18
L = 666 cm²
Luas trapesium
= ½ x ( a + b ) x t
= ½ x ( 14 + 37) x 18
= 51 x 9
= 459 cm²
Luas yang diarsir=> 666 - 459 = 207 cm²
Luas yang diarsir adalah 207 cm²
LR = (P(L) - (1/2(A + B(T)
= (37(18) - (1/2(14 + 37(18)
= 666 - (1/2(51(18)
= 666 - (1/2(918)
= 666 - (918/2)
= 666 - 459
= 207 CM²
