Question

Find the area of that square whose diagonal is 7√2m

Answer 1

Answer:

Step-by-step explanation:

Diagonal of square =7 root 2

Let the side of square be x

The angles of square are right angle

So,

By pythagoras theorem

x^2 + x^2 = diagonal^2

2x^2=(7 root 2)^2

2x^2=49× 2

2x^2=98

X^2=98/2

x^2=49

Taking a square root

x=7

x is side of square =7cm

Area of square =side^2

=7^2

Area of square=49cm^2
