Question

$find \: the \: area \: of \: a \: square \: whose \: \\ diagonal \: is \: 5 \sqrt{2} cm$
​

Answer 1

Diagnol of square with side a = a (root2)

Side of square = a = ?

a(root2)=5(root2)

a = 5cm

Area of square = a2

= (5)square

= 25

Area of square = 25 sq cm.

Answer 2

Answer: is 25cm²

Step-by-step explanation: Diagonal = 5√2cm

                                             side×√2 = 5√2cm

                                              side   = 5cm

area of square =side²

                          =  5²   =25cm²
