( b ) Perimeter = Sum of all sides
28 cm = 4 cm + 5 cm + 9 cm + x cm
28 cm = 18 cm + x cm
28 cm - 18 cm = x cm
10 cm = x cm
Therefore, the other side = 10 cm
( c ) Perimeter = Sum of all sides
49 cm = 7 cm + 7 cm + 28 cm + x cm
49 cm = 42 cm + x cm
49 cm - 42 cm = x cm
7 cm = x cm
Therefore, the other side = 7 cm
