Answer:
0.0707 cm
Step-by-step explanation:
We can solve this using pythgaoras theorem:
a² + a² = c² (We can use the same letter, a, because the lengths are the same length; a² + a² = 2a²)
2a² = 0.1² (simplify the right side; 0.1 × 0.1 = 0.01)
2a² = 0.01 (0.01 ÷ 2 = 0.005)
a² = 0.005 (square root both sides)
a = 0.070710... ≈ 0.0707 cm
Hope this helps!
