tolong jawab gambar diatas

Penyelesaian :

Panjang persegi panjang
= ( K ÷ 2 ) - Lebar
= ( 130 cm ÷ 2 ) - 30 cm
= 65 cm - 30 cm
= 35 cm

Luas persegi panjang
= p × l
= 35 cm × 30 cm
= 1050 cm^2

Good Luck :)

jwb = panjang persegi
panjang = (k ÷ 2)- lebar = (130cm ÷ 2)- 30cm=65cm-35cm
P×L = 35cm× 30cm = 1050cm²
