Question

If the Length of the diagonal of a square is 6CM , then its perimeter will be

Answer 1

Answer:

4√3

Step-by-step explanation:

Length of diagonal = 6 cm

Applying Pythagoras theorem as the angle between two adjacent sides of square is 90° and the diagonal forms a right angled triangle,

2×(x^2) = 6^2 =36 => x = 3√2 ,

where x is the length of side of square

perimeter of square = 4 × x = 4 × 3√2

= 12(√2)
