Answer 2

Since the perimeter of square is 48m.
The side of the square would be, 48÷4=12m.
Therefore, the area of square would be, 12×12=144m^2.

The area of rectangle is 4 less than of square, i.e. 144-4=140m^2.
The area of rectangle, is length ×breadth.

14×breadth=140m^2.

breadth=140÷14=10m.

Thus, the breadth of rectangle is 10m.
