>>--------☺️-------<<

we know that area of square is side × side

but what we are given is just diagonal.

we can find the sides of the square by applying the Pythagoras theorem.

which is:

H^2 = P^2 + B^2

( H × H = P × P + B × B )

14^2 = P^2 + P^2.( since the sides of square are equal )

14 × 14 = 2P^2

196/2 = P^2

98 = P^2

P = √98

P = 7√2 cm = sides of square.

now, area of square = side × side

= 7√2 × 7√2

=49 × 2

= 98

Answer 2

Diagonal area formula =

$\frac{d {}^{2} }{2}$

NOW DO

$\frac{14 \times 14}{2} = 98$

Hope it's helpful to u
