In the adjoining figure, angle BAC = 90°,
AC = 400 m and AB = 300 m. Find the
length of BC.

( step by step )​

Answer 1

Answer:

$\huge\colorbox{yellow}{Given\:-}$

AC = 400 m

AB = 300 m

$\huge\colorbox{yellow}{To\:Find\:-}$

BC

$\huge\colorbox{yellow}{Solution\:-}$

$\small\underbrace\mathrm\red{By\:Pythagoras\:Theorem}$

${bc}^{2} = {ab}^{2} + {ac}^{2}$

${bc}^{2} = {(300)}^{2} + {(400)}^{2}$

${bc}^{2} = 90000 + 160000$

${bc}^{2} = 250000$

$bc = \sqrt{250000}$

$\small\colorbox{pink}{BC\:=\:500\:m}$
