Question

plis tolong jawab kan dong saya lagi ulangan dan lupa rumusnya

Answer 1

Jawaban:

1) K = 32 m

S = 32/4 = 8 m

Luas = s x s

= 8 x 8

= 64 m²

2) Panjang jalan = 14 m

Lebar = 7 m

Luas jalan = p x l

= 14 m x 7 m

= 98 m²

3) S = 16 m

Keliling = 4s

= 4 x 16

= 64 m

Banyak pohon

= 64/3

= 21 pohon
