Question

Hitunglah:
a. pnjang AB
b. pnjang QR

dng 2trapesium siku2 yg sebangun
dng ukuran (yg bsr) :alas/PQ;16& sisi atas/SR;12(trapesium PQRS) &
ukuran(yg kcl); sisi miring/AD;4&sisi atas/DC;6 (trapesium BADC)
dng tuliskan caranya ya

Answer 1

PQRS sebangun dg BACD
SR=12 cm , CD=6 cm
SR : CD = 12 : 6 = 2 : 1
a) PQ : BA = 2 : 1 = 16 : x
x = 16/2 = 8 cm
b) QR : DA = 2 : 1 = x : 4
x = 4.2 = 8 cm
 semoga membantu :)
