tolong dijawab ya dengan cara nya mksh

1. L.segitiga = 1/2 × alas × tinggi
= 1/2 × 14 × 16 = 112
2. L.segitiga = 1/2 × alas × tinggi
42 cm^2 = 1/2 × alas × 12
42 cm^2 = 6 × alas
alas = 42 : 6 = 7
3. L.segitiga = 1/2 × alas × tinggi
96 cm^2 = 1/2 × 12 × tinggi
96 cm^2 = 6 × tinggi
tinggi = 96 : 6 = 16
4. L.segitiga = 1/2 × alas × tinggi
= 1/2 × 24 × ( akar alas - tinggi)
= 12 ( akar 24 - 20 )
= 12 (akar 4 )
= 12 × 2
= 24
5. k.segitiga sama kaki = alas + 2× sisi
16 = 6 + 2×sisi
2 × sisi = 16 - 6
2 × sisi = 10
sisi = 10 : 2 = 5
L.segitiga = 1/2 × alas × 2sisi
= 1/2 × 6 × 2 × 5
= 30
maaf kalo salah.........
