Question

A square has a perimeter of 124cm calculate the lenght of its side and calculate its area​

Answer 1

Answer:

31cm,  961 cm^2

Step-by-step explanation:

Let the length of the side of the square be 'a'.

  Using, perimeter of square = 4a

⇒ perimeter = 124cm

⇒ 4a = 124 cm

⇒ a = (124/4) cm = 31 cm

    Side of the square is 31 cm

Area of square = side^2 = a^2            

                         = (31cm)^2

                         = 961 cm^2

Answer 2

P= 4a
124 =4*a
124/4=a
31=a
Now, area = 2asq
Area = 2*31*31
= 2*961
