Jawab:

Penjelasan dengan langkah-langkah:

3.

=1/2×a×t + 1/2×a×t - 2(1/2×a×t)

=1/2×5×12+1/2×5×8 - 2(1/2×5×4)

=5×6+5×4-2(5×2)

=30+20-2(10)

=30+20-20

=30

4.

28-12=16

16/2=8

tinggi=√17²-8²

=√289-64

=√225

=15

L. Trapesium= 1/2×(a+b) ×t

= 1/2×(12+28)×15

=1/2×40×15

= 20×15

= 300

semoga membantu :)
