Question

A square paper is folded into half,breadthwise. The perimeter of the rectangle formed is 12cm.what is the area of the square?

Answer 1

Answer:

Let the sides of the square be 'x'.

We have,

Perimeter of the rectangle= 12cm

=> 2 (l + b)= 12

=> 2 (x/2 + x)= 12

=> 2 (x + 2x)/2= 12

=> 2 (3x/2)= 12

=> 3x= 12

=> x= 12/3

=> x=4cm

.·. Area of the square= (4*4)cm^2

=16cm^2
