tolong bantu kakak baikk​

Lebar persegi panjang:

L = p × l

24 = 8 m × l

l = 24 m ÷ 8 m

l = 3 m

Maka,

Keliling persegi panjang:

K = 2 × ( p + l )

K = 2 × ( 8 m + 3 m )

K = 2 × 11 m

K = 22 m

》Luas dan Keliling

Lebar = Luas ÷ Panjang

• = 24 m² ÷ 8 m
• = 3 m

Keliling = 2 ( Panjang + Lebar )

• = 2 ( 8 + 3 )
• = 2 ( 11 )
• = 22 meter
