Jawaban:

p = 3,2 dam = 32m

l = 250 dm = 25m

Keliling kebun

[tex] = 2(p + l) \\ = 2(32 + 25) \\ = 2(57) \\ = 114m[/tex]

Jawaban C

-Bangun Ruang-

Rumus keliling persegi panjang= P × L

P= 3,2 dam = ... m

dam = × 10 m

3,2 × 10 = 32 m

L= 250 dm = ... m

dm = ÷ 10 m

250 ÷ 10 = 25 m

K = 2 × ( P + L )

2 × ( 32 + 25 )

2 × ( 57 )

= 114 m
