Correct Answer: 68 cm2
Solution : The outer square has sides of length 18 cm, so its area is 18 × 18 cm2. The inner square, formed by the 1 cm wide path along the edges, has sides = 18 − (2 × 1) = 16 cm The area of the inner square is = 16 ×16 cm2 Area of path = Area of the outer square − Area of the inner square = (18 × 18) − (16 × 16) = 324 − 256 = 68 cm2 Hence, the correct answer is 68 cm2.
