Answer 2

Answer:

The correct answer is option (4) 8cm

Step-by-step explanation:

Breadth of rectangle = Side of square

Let the side of square be x cm.

Perimeter of square = 4 x side

24 = 4x

x = 24/4

x = 6 cm

Side of square = Breadth of rectangle = 6 cm

Let the length of rectangle be l cm.

Perimeter of rectangle = 2 x (l + b)

28 = 2x(l+6)

28/2 = l+6

14 - 6 = l

l = 8cm
