Dik:
- panjang salah satu diagonal belah ketupat (d1) = 15
- Luas = 60 cm²
Dit:
- panjang diagonal yg lainnya (d2)?
Dijawab:
L = 1/2 × d1 × d2
60 cm² = 1/2 × 15 × d2
60 cm² = 15/2 × d2
d2 = 60 ÷ 15/2
d2 = 60 × 2/15
d2 = 8 cm
Ket:
L = Luas
d1 = diagonal 1
d2 = diagonal 2
~VVM
Penyelesaian ☁️
Luas = ½ × d1 × d2
60 = ½ × 15 × d2
60 = 15/2 × d2
d2 = 60/15/2
d2= 60 × 2/15
= 8 cm
