Mohon dibantu ya!! pada layang layang PQRS, PQ:20 cm, Qs:24 cm, luasnya 252 cm².

A) L = 1/2 x d1 x d2
L = 1/2 x QS x PR
252 = 1/2 x 24 x PR
252 = 12 x PR
PR =252/12
PR = 21 cm

b) PO² = PQ² – QO²
PO² = 20² – 12²
PO² = 400 – 144
PO² = 256
PO =√256
PO = 16 cm

c) L Δ = 1/2 L layang²
L Δ = 1/2 252
L Δ = 126 cm

L Δ = 1/2 x a x t
L Δ = 1/2 x PQ x QR
126 = 1/2 x 20 x QR
126 = 10 x QR
QR = 126/10
QR = 12,6 cm

maaf klw salah, semoga membantu 🙂
