Tolong pakai cara kak. trims.

AO = CO = 18 cm
BD = 45 cm

d1 = AC = 18 + 18 = 36 cm
d2 = BD = 45 cm
Luas layang-layang = 1/2 x d1 x d2
L = 1/2 x 36 x 45
L = 810 cm^2

Penyelesaian :
AO = CO = 18 cm
BD = 45 cm

Luas layang layang
= 1/2 × ( AO + CO ) × BD
= 1/2 × ( 18 cm + 18 cm ) × 45 cm
= 1/2 × 36 cm × 45 cm
= 810 cm^2 ✔
