nomor 25 dan 26 gimana ya makasiih

25.
[tex] \frac{PQ}{AD} = \frac{PR}{AB} [/tex]
[tex]\frac{4}{8} = \frac{PR}{20}[/tex]
[tex]\frac{1}{2} = \frac{PR}{20}[/tex]
2PR = 20
PR = 10

[tex] \frac{PQ}{AD} = \frac{BC}{RS} [/tex]
[tex]\frac{4}{8} = \frac{BC}{10}[/tex]
[tex]\frac{1}{2} = \frac{BC}{10}[/tex]
2BC = 10
BC = 5

[tex] \frac{PQ}{AD} = \frac{QS}{CD} [/tex]
[tex]\frac{4}{8} = \frac{QS}{14}[/tex]
[tex]\frac{1}{2} = \frac{QS}{14}[/tex]
2PR = 14
PR = 7

Keliling trapesium PQRS = PQ+PR+RS+SQ = 4+10+5+7 = 26 (C)

26. C. [tex] \frac{PQ}{PR} = \frac{XY}{XZ} [/tex]
