Question

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

Answer 1

Any problem then ask to me again!!!

diagonal of square = 5√2

√2 a = 5√2 (formula of diagonal of square is √2 a ,where a is side of square)

Comparing above statement,we get

a = 5cm

Area of square = a^2

= 5^2

= 25 cm

Hence, Area of square is 25cm.
