Step-by-step explanation:

Given c = longest of triange = 15m

Given b = short side of triangle = 9m

By pythagoras' Theorem,

${c}^{2} = {a}^{2} + {b}^{2} \\ {a}^{2} + {b}^{2} = {c}^{2} \\ {a}^{2} + {(9)}^{2} = {(15)}^{2} \\ {a}^{2} + 81 = 225 \\ {a}^{2} = 225 - 81 \\ {a}^{2} = 144 \\ a = \sqrt{144} \\ = 12m$
