jawab ya pliss dengan caranya

1.

L1 = p × l
L1 = 80 × 30
L1 = 2400

L2 = p × l
L2 = 40 × 10
L2 = 400

Luas Total 2400+400 = 2800 cm²

Keliling = 40+40+10+40+30+80 = 240 cm²

2.

L = p × l
L = 7 × 5
Luas = 35 cm²

Keliling 7+5+7+5 = 24 cm²


Semoga Bermanfaat :)

1.(s×s)+(p×l)=(30×30)+(40×80)=900+3200=
4.100cm2

2.(7×2,5)+(7×2.5)=17,5+17,5=35cm2
