Tolong di bantu yh kakak

Aku bantu jawab ya;⁠) Diketahui = PQ : RS = 7 : 2 PS = 8 cm -> tinggi trapesium L = 108 cm² Ditanya = K ? Jawab = L = ½ × (a + b) × t 108 = ½ . ( PQ + RS) . 8 ( PQ + RS) = 108 : (8 .½) ( PQ + RS) = 108 : 4 ( PQ + RS) = 27 PQ = 7/9 × 27 PQ = 21 cm RS = 2/9 × 27 RS = 6 cm RQ² = (21 - 6)² + 8² RQ² = 225 + 64 RQ = √289 RQ = 17 cm K = PS + SR + RQ + QP K = 8 + 6 + 17 + 21 K = 52 cm Jadi keliling trapesium adalah 52 cm
