Question

find the area and length of the diagonal of a sqaure having sides 4.5cm​

Answer 1

Answer:

Area of Square = s^2

                          = 4.5 * 4.5

                          = 20.25 cm^2

Diagonal of Square = √ 2 * s

                                  = √ 2 * 4.5

                                  = 6.36396 cm

Hope it will help you...

Answer 2

Step-by-step explanation:

area of sqaure = a^2

4.5×4.5

= 20.25cm^2

length of diagnol we find out by pgt theorem

diagnol^2 = (4.5)^2+(4.5)^2

= 6.36cm
