| a | 2 cm | 7 mm | 20 m | 5 mm | 6 dm | 20 cm |
| Pole kwadratu o boku a | 4 cm2 | 49 mm2 | 400 m2 | 25 mm2 | 36 dm2 | 400 cm2 |

Obliczenia:
I.
a = 2 cm
P = (2 cm)2 = 4 cm2
O = 4 · 2 cm = 8 cm
II.
a = 7 mm
P = (7 mm)2 = 49 mm2
O = 4 · 7 mm = 28 mm
III.
a = ?
P = (a)2 = 400 m2 / √
a = 20 m
O = 4 · 20 m = 80 m
IV.
a = ?
P = (a)2 = 25 mm2 / √
a = 5 mm
O = 4 · 5 mm = 20 mm
V.
a = ?
O = 4 · a = 24 dm / : 4
a = 6 dm
P = (a)2
P = (6 dm)2 = 36 dm2
VI.
a = ?
O = 4 · a = 80 cm / : 4
a = 20 cm
P = (a)2
P = (20 cm)2 = 400 cm2
