Answer 2

Answer:

let ABC is a right angled at B

by using Pythagoras therum

$= > {hypoteneus}^{2} = {perpendicular}^{2} + {base}^{2} \\ = > {ac }^{2} = {bc}^{2} + ab^2 \\ = > {15}^{2} = {9}^{2} + {ab}^{2} \\ = > 225 = 81 + {ab}^{2} \\ = > 225 - 81 = {ab}^{2} \\ = > \sqrt{144} = ab \\ = > ab = 12cm$
