Please di jawab besok di kumpul

Answer 1

Verified answer

Luas persegi panjang
= 8 x 13
= 104 cm²

Luas trapesium
= ( 10 + 13 ) x 4 / 2
= 23 x 2
= 46cm²

Luas keduanya
= 104 + 46
= 150 cm²

Answer 2

L. trapesium = 1/2 * (a+b) * t = 1/2*(8+12)*3 = 1/2 * 20 * 3 = 30 cm'2
l. persegi panjang : p * l = 10 * 12 = 120 cm'2
luas bangun datar : 30+120 = 150 cm'2
