Answer 1

Answer:

Perimeter of Square = 80cm

Answer 2

Answer:

Length of the rectangle=40
The breadth of the rectangle= 10

Since it is given that the area of the square is the same as the rectangle

Therefore

Area of rectangle= l x b = 40 x 10 = 400 cm square

There area of square = area of rectangle (given)

Area of square = 400 cm square

=>X square = 400 cm square

=> X = 20 cm

Therefore the perimeter of square = 4 X = 4 x 20 = 80 cm
