Question

There is a large square portrait of a leader that covers an area of 4489 cm². If each side has a 2 cm liner, what would be its area?

Answer 1

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
