PR = 25 cm
SQ = 24 cm
RT = 16 cm
Dit. K ?
jwb :
1) Mencari panjang sisi PQ :
PT = PR - RT
PT = 25 cm - 16 cm
PT = 9 cm
QT = 12 cm
2) Mencari panjang sisi QR :
QT = 12 cm
RT = 16 cm
K = 2 (a + b)
K = 2 (15 cm + 20 cm)
K = 2 . 35 cm
K = 70 cm
Jika digambarkan, layang layang PQRS adalah sebagai berikut :
