Question

find the length of the diagonal of a square whose each side measures 11 cm​

Answer 1

Answer:

The length of the diagonal of a square is 15.55cm

Step-by-step Explanation :

Given : Side of square = 11cm

To find : length of diagonal = ?

We know that,

The angle formed between two adjacent side's of square is 90°

So we can apply Pythagoras theorem,

(Diagonal)² = (side)² + (side)²

= 11² + 11²

= 121 + 121

(Diagonal)² = 242

By taking square root on both the sides we get

Diagonal = 15.55cm

Hence the length of the diagonal of a square is 15.55cm
