Answer :
Answer: 8.49cm
Step-by-step explanation:
Given Data:
Let a be no of side = 6
Therefore
d = √2 * a
d = √2 * 6
d = 1.4142 * 6
d = 8.49cm
The diagonal is 8.49cm
Answer:
The length of the diagonal of a square of length 6 cm is 6√2 cm = 8.485 cm
Step-by-step explanation:
English Translation
Determine the length of the diagonal of a square with a side of 6 cm.
Solution
Let the length of the diagonal be d.
And the length of each side of the square be s.
Note that s = 6 cm
The two sides of the square and the diagonal form a right angled triangle with the diagonal serving as the hypotenuse.
Using Pythagoras theorem, the square of the hypotenuse is equal to the sum of the individual squares of the two other sides of the right angled triangle.
d² = s² + s²
d² = 2s²
d = √(2s²)
d = s √2
note that s = 6 cm
d = 6 × √2 = 6√2 cm = 8.485 cm
Hope this Helps!!!
