pakai cara ya​

Answer 1

Jawaban:

1.) K = s + s + s + s

= 7 + 7 + 7 + 7

= 28 cm

2.) K = a + b + c

= 9 + 9 + 9

= 27 cm

3.) K = p + l + p + l

= 20 + 5 + 20 + 5

= 50 cm

4.) K = a + b + c

= 4 + 5 + 3

= 12 cm

5.) K = a + b + c

= 14 + 16 + 12

= 42 cm

Answer 2

1. Keliling = 4s = 4 x 7 cm

Keliling = 28 cm

2. Keliling = a + b + c

Keliling = 9 cm + 9 cm + 9 cm

Keliling = 27 cm

3. Keliling = 2 (p + l)

Keliling = 2 (20 cm + 5 cm)

Keliling = 2 x 25 cm

Keliling = 50 cm

4. Keliling = a + b + c

Keliling = 3 cm + 4 cm + 5 cm

Keliling = 12 cm

5. Keliling = a + b + c

Keliling = 12 cm + 14 cm + 16 cm

Keliling = 42 cm
