| 67 | 4489 |
| 67 | 67 |
| 0 |
Area of the square = 4489 cm2
(side)2 = 4489 cm2
(side)2 = 67 × 67
side2 = 672
Length of a side = 67
Length of a side with liner = 67 + 2 + 2 cm
= 71 cm
Area of the larger square = 71 × 71 cm2
= 5041 cm2
Area of the liner = Area of big square – Area of small square
= (5041 – 4489) cm2
= 552 cm2
