perhatikan gambar disamping! Luas trapesium ABCD adalah.... (tolong dijawab pake cara)

cari t nya
[tex]t= \sqrt{ 13^{2} - 5^{2} }
t= \sqrt{169-25}
t= \sqrt{144}
t=12[/tex]

[tex]L= \frac{(a+b)}{2} [/tex]×t
[tex]L= \frac{(25+15)}{2} [/tex]×12
[tex]L= \frac{40}{2} ×12
L= 20 ×12
L= 240 cm^2

semoga membantu ^^

L trapesium = (A + B) T / 2
kita cari T^2= 13^2 - 5^2
T^2= 169 - 25
T^2 = 144
T = 12
[tex]l = \frac{(15 + 20).12}{2} [/tex]
[tex]l = \frac{35 \times 12}{2} \\ l = 35 \times 6 \\ l = 210[/tex]
semoga bermanfaat dan membantu
