PS = √(25-16)² + (24/2)²
PS = √9² + 12²
PS = √81 + 144
PS = √225
PS = 15 cm
RS = √TS² + TR²
RS = √12² + 16²
RS = √144 + 256
RS = √400
RS = 20 cm
Keliling = QP + PS + SR + RQ
= 15 + 15 + 20 + 20
= 70 cm
d₁ = PR
d₂ = QS
Luas = 1/2 x d₁ x d₂
= 1/2 x 25 x 24
= 300 cm²
QT = 1/2.SQ = 1/2.24 = 12 cm
maka:
PQ = PS = akar dr PT²+QT²
= akar dr 9²+12²
= akar dr 81+144
= √225
= 15 cm
QR = RS = akar dr QT²+RT²
= akar dr 12²+16²
= akar dr 144+256
= √400
= 20 cm
jadi, K = PQ+PS+QR+RS
= 15+15+20+20
= 70 cm
dan
L = 1/2.d1.d2
= 1/2.SQ.PR
= 1/2.24.25
= 12.25
= 300 cm²
