Question

The diagonal of a square is 472 cm, then find the following:
(i) Length of each side
(ii) Perimeter of square​

Answer 1

Diagonal of square = √2a [a = side]

4√2 = √2 a

a = 4 cm

Now, area of square = a2 = (42) = 16

Side of a square whose area is 2 x 16.

a12 = 32

⇒ a1 = √32 ⇒a14√2

Now, diagonal of new square = √2a

= √2x 4 √2

= 8 cm
