Question

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

Answer 1

The area would be 4761 cm²

Step-by-step explanation:

We know that,

Area of a square,

A = s²,

Where,

s = side length of the square,

If A = 4489 cm²,

4489 = s²

$\implies s =\sqrt{4489}=67\text{ cm}$

If side is increased by 2 cm,

s = 67 + 2 = 69 cm,

Then area of the square,

$A=69^2 = 4761\text{ square cm}$
