Tolong dijawab ya...aku butuh banget nih?......

Answer 1

1)
Luas
= 1/2 x (a+b) x t
= 1/2 x (5+10) x 6
= 3 x 15
= 45 cm²


2)
Luas
= 1/2 x (a+b) x t
= 1/2 x (17+40) x 20
= 10 x 57
= 570 cm²

Answer 2

1.(a+b)×t÷2=(5+10)×6÷2=15×6÷2=90÷2=45 cm2 2.(a+b)×t÷2=(17+40)×20÷2=57×20÷2=1140÷2=570 cm2.semoga dapat membantu.
