Answer 2

Answer:

(i) Perimeter = 4 × side = 4× 12cm = 48 cm

Area = side × side = 12cm × 12cm = 144cm square

(ii) Perimeter = 4 × side = 4× 4.2m = 16.8 m

Area = side × side = 4.2 ×4.2m = 17.64m square

(iii) Perimeter = 4× side = 4× 3.5dm = 14dm

Area = side × side = 3.5 × 3.5 dm = 12.25 dm square
