Question

find the area of a square whose diagonal is 5.2 cm​

Answer 1

Step-by-step explanation:

Side of square = diagonal/√2

Area=(diagonal /√2)^2

=(5.2)^2/2

=27.04/2

=13.57 cm sq.

Answer 2

• As per the data given in the question, we have to determine the area of a square.

       Given data:- Diagonal=$5.2cm.$

       To find:- Area of square=?

       Solution:-

• We know that,A square has four sides and each sides are equal and parallel to each other.
• Area of the square=$(side)^{2}.$
• Side of square=$\frac{Diagonal}{\sqrt{2} }.$

        Therefore,

           $a^{2}=(\frac{Diagonal}{\sqrt{2} })^{2}\\=\frac{5.2^{2} }{2}\\=\frac{27.04}{2}\\=13.52cm^{2}.$

      Hence, the area of the square will be $13.52.$
