Perimeter of a square = (4 × side) units
Area of a square = (side × side) unit2
(i) s = 6 cm
Perimeter = 4s units = 4 × 6 cm = 24 cm
P = 24 cm
Area = s × s unit2 = 6 × 6 cm2 = 36 cm2
A = 36 cm2
(ii) Perimeter = 4 × s unit
100 = (4 × s) m
100/4 = s
s = 25 m
Area = s × s unit2= 25 × 25 m2 = 625m2
A = 625m2
(iii) Area = s × s unit2
49 = s × s square feet
s2 = 72
s = 7 feet
Perimeter = 4 × s unit = 4 × 7 feet = 28 feet
Perimeter = 28 feet
