Answer 1

Jawaban:

1. K : 4

= 80 : 4

= 20 cm

2. Sisi = K : 4

= 100 : 4 = 25 cm

3. Lebar = Luas : p

= 225 : 25 = 9 cm

4. Lebar = K : 2 - p

= 150 : 2 - 50 = 25 cm

5. panjang = Luas : lebar

= 300 : 15 = 20 cm

6. Tinggi = Luas × 2 : alas

= 108 × 2 : 18 = 12 cm

7. Sisi = K : 3

= 60 : 3 = 20 cm

8. 126 - 48 - 48 = 30 cm

9. Panjang = K : 2 - l

= 236 : 2 - 62 = 56 cm

10. Lebar = Luas : p

= 950 : 38 = 25 cm
