Question

Tolong dibantu ya kaka kaka pintar matematika ​

Answer 1

AB = DE = 13 sehingga CD = CE + DE = 13 + 12=25
keliling = AB + BC + CD + DA
= 13 + 3 + 12 + 8
= 16 + 20
= 36
L = 1/2 × jumlah rusuk sejajar × tinggi
=1/2 × 12 ×8
= 6 × 8
= 48
#semoga membantu# maaf kalau salah#

Answer 2

Jawab:

Penjelasan dengan langkah-langkah:

AB = DE = 13 sehingga CD = CE + DE = 13 + 12=25

keliling = AB + BC + CD + DA

= 13 + 3 + 12 + 8

= 16 + 20

= 36

L = 1/2 × jumlah rusuk sejajar × tinggi

=1/2 × 12 ×8

= 6 × 8

= 48
