Keliling persegi panjang
100 = 2 × ( p + l )
100 = 2 × ( p + 30 )
100 = 2 × ( 20 + 30 )
100 = 2 × 50
100 = 100
•Jadi panjang sisi nya adalah 20 cm (A)
•Mudah kan??
•Semoga membantu ya...
Keliling segitiga = a + b + c
K = a + b + c
K = 20 cm + 30 cm + 40 cm
K = 50 cm + 40 cm
K = 90 cm
Keliling persegi panjang = 2 × ( p + l )
K = 2 × ( p + l )
100 cm = 2 × ( p + 30 cm )
Semoga Bisa Bermanfaat-!
