Jawaban:
1. 18x3=54
2. 2x(5+15) = 40
3. 2x(24+16) = 80
4. 28x4= 112
5. 2x(13+25) = 76
6. 2x(10+24) = 68
7. d= πx2
= 14x2= 28
k= πxd
= 22/7 x 28= 88
Jawab:
1. 54 cm
2. 40 cm
3. 80 cm
4. 104 cm
5. 76 cm
6. 68 cm
7. 87,92 cm
Penjelasan dengan langkah-langkah:
1. Keliling Segitiga = s + s + s
= 18 + 18 + 18
= 54 cm
2. Keliling Persegi Panjang = 2 x ( p + l )
= 2 x (15 + 5)
= 2 x 20
= 40 cm
3. Keliling Trapesium = a + b + c + d
= 24 + 16 + 24 + 16
= 80 cm
4. Keliling Persegi = 4 x s
= 4 x 28
= 104 cm
5. Keliling Persegi Panjang = 2 x (p + l)
= 2 x (13 + 25)
= 2 x 38
= 76 cm
6. Keliling Layang Layang = 2 x (a + b)
= 2 x (10 + 24)
= 2 x 34
= 68 cm
7. Keliling Lingkaran = 2 x π x r
= 2 x 3,14 x 14
= 87,92
