Question

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

Answer 1

Dear Student,

◆ Answer -

Area of lining = 272 cm^2

● Explanation -

Let x be side of the square.

Area of the square portrait is -

A1 = x^2

4489 = x^2

x = √4489

x = 67 cm

Area of the lining is -

A = A2 - A1

A = (x+2)^2 - x^2

A = (67+2)^2 - 67^2

A = 4761 - 4489

A = 272 cm^2

Hence, area of the square lining is 272 cm^2.

Thanks dear. Hope this helps you..
