Answer :
(I) 4 cm
Step-by-step explanation :
Given,
- Side of the square, a = 2√2 cm
To find,
- the diagonal
Solution,
Let the side of the diagonal be "d cm"
Side of the square, a = 2√2 cm
By Pythagoras theorem, (Δ BCD)
(BD)² = (BC)² + (CD)²
d² = a² + a²
d² = 2a²
d = √2a
Substitute, a = 2√2 cm
d = √2 (2√2 cm)
d = 2(√2)² cm
d = 2(2) cm
d = 4 cm
The length of the diagonal is 4 cm
