Alas : Tinggi = 3:4
Panjang alas = 0,64 m = 64 cm
⬇️Cara⬇️
3 : 4 = 64 : Tinggi
¾ = 64/T
¾ T = 64
T = 64/(¾)
T = 64x(⁴/3)
T = 256/3
T = 85 ⅓ cm
Luas segitiga ABC
½ x Alas x Tinggi
= ½ x 64 cm x 85 ⅓ cm
= 32 cm x 85 ⅓ cm
= 32 x 85 ⅓
= 32 x 256/3
= 8.192/3
= 2.730 ⅔ cm² <= Jawaban
Jadi, luas segitiga ABC adalah 2.730 ⅔ cm²
