Luas belah ketupat = ½ × d1 × d2120cm² = ½ × 24cm × d2
120cm² = 12cm × d2
d2 = 120cm² ÷ 12cm
d2 = 10cm
Sisi belah ketupat
= √(12cm)²+(5cm)²
= √144cm²+25cm²
= √169cm²
= 13cm
Keliling belah ketupat
= 4 × sisi
= 4 × 13cm
= 52cm
Semoga bermanfaat.
SELAMAT BELAJAR!! ^_^

K = 13 x 4 = 52cm
keliling belah ketupat adalah 52cm.
