= 22cm.
untuk membuktikan =
17cm × 22cm ÷ 2
= 187cm²
Rumus luas layang-layang adalah:
L = 1/2 × diagonal 1 × diagonal 2
Diketahui:
L = 187 cm^2
d2 = 17 cm
Ditanya:
d1
Jawab:
L = 1/2 × d1 × d2
187 = 1/2 × d1 × 17
pindahkan 2 yg dari 1/2 ke kiri
187 × 2 = 1 × d1 × 17
374 = d1 × 17
berarti
d1 = 374 / 17
d1 = 22
Semoga membantu^^
