Penjelasan dengan langkah-langkah:
a.
Luas
= ½ x 24 x 32
= 384 cm²
b.
Keliling
= 4s
mencari s
s = √(16²+12²)
s = √(256+144)
s = √400
s = 20 cm
maka keliling
= 4 x 20
= 80 cm
A) L :
= 1/2D1D2
= 1/2(24(32)
= 1/2(768)
= 768/2
= 384 CM²
B) S = √16² + 12²
= √(16(16) + (12(12)
= √256 + 144
= √400
= √20²
= 20
MAKA :
K = 4(20)
= 80 CM
