Answer:
well by Pythagoras theorem A^2+B^2=C^2
SO,
24^2+18^2=BC^2
576+324=BC^2
900=BC^2
BC=Root of 900
BC=30cm

Given: ∆ABC right angled at A and AB = 18 cm, AC = 24 cm.
To find: Length of BC.
According to Pythagoras Theorem,
BC2 = AB2 + AC2
= 182 + 242 = 324 + 576 = 900
∴BC = √900 = √ 30x30 = 30 cm
