halo, tolong bantu dong, pakai cara
[tex] \tt = \frac{(a + b) \times t}{2} [/tex]
[tex] \tt = \frac{(12 + 17) \times 8}{2} [/tex]
[tex] \tt = \frac{29 \times 8}{2} [/tex]
[tex] \tt = \frac{232}{2} [/tex]
= 116 cm² (A.)
[tex]\purple{\boxed{\blue{\boxed{\green{\star{\orange{\ \: \: \mathcal{JK} \: \: \: {\green{\star}}}}}}}}} [/tex]
Jawaban:
A. 116
diketahui:
alas atas = ada = 12 cm
alas bawah = ab = 17 cm
tinggi = t = 8 cm
Luas = ½(aa+ab)×t
Luas = ½(12+17)×8
Luas = ½(29)×8
Luas = 116 cm²
