Question

the square of a diagonal 128 cm find the side of a square​

Answer 1

Answer:

∴ The side of a square is $90.50$ cm.  

Step-by-step explanation:

In context to question given,

• We have to find the side of a square.
• The diagonal of a square = $128$ cm
• As we know that square has four sides and the length of each side is same.
• The diagonal of a square is the line which joins two vertices of a square which are non adjacent to each other.
• The formula for diagonal of a square is given by,

         Diagonal of a square = $\sqrt{2} *a$

Where $a$ is the side of a square.

                                   ∴ $a=\frac{d}{\sqrt{2} }$

                                        = $\frac{128}{\sqrt{2} }$

                                        = $90.50$ cm

• ∴ The side of a square is $90.50$ cm.
