Question

if the diognal of square is 10cm then find its side ​

Answer 1

Answer:

5√2 cm

Step-by-step explanation:

Let the side of square be x cm.

We know that all sides of square are equal and all angles are of measure 90° .

By Using PGT ( Pythagoras Theorem),

side² + side ² = diagonal²

x²+ x² = diagonal²

2x² = 10²

2x²= 100

x²= 50

x = √ (25× 2)

x = 5√2

Thus, Side of square is 5√2 cm.
