It depends on what B is and what S is!
Perimeter = 28 = 4s = 4 x 7 Therefore, each side is 7cm long Area = s x s = 7 x 7 = 49cm squared
7 cm x 3 sides = 7 x 3 = 21 cm perimeter.
If it is a square, with side (s) length 2.5 units, then perimeter = 4*s = 10 units. Area = s2 = (2.5 units)2 = 6.25 square units.
