Question

Find the area, in square centimetres, of a square whose side is
(i) 2.6 cm
(ii) 1.2 dm

Answer 1

We have,
(i) Side of the square = 2.6 cm
Therefore, area of the square = (Side)²
= (2.6 cm)² = 6.76 cm²


(ii) Side of the square = 1.2 dm = 1.2 x 10 cm = 12 cm [ Since 1 dm = 10 cm]
Therefore, area of the square = (Side)²
= (12 cm)² = 144 cm²
