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 outer lining is 272 cm^2.
Thanks dear. Hope this helps you..
