104 = 4 x s
s = 104 : 4
= 26
panjang bd = √ 26² - 24²
= √ 676 - 576
= √ 100
= 10 x2 = 20cm
L. bela ketupat = d1 x d2
2
= 48 x 20
2
= 480cm²
panjang diagonal yang lain adalah √26² - 24² = 10
jadi panjang diangonal yang lain adalah 2 x 10 = 20
luas belah ketupat = 1/2 x (diagonal 1 x diagonal 2)
= 1/2 x (48 x 20)
= 480
