Answer 1

Question:-

Find distance of point (a, 2a) from origin.

$\huge\pink{\boxed{\blue{\mathcal{{{{\underline{Answer}}}}}}}}$

Given:

• Here we have given a two points ( a , 2a )
• The other points are not given so let it be ( 0 , 0 )

To find:

• The distance from origin

For this we will use distance formula.

$\bigstar \sqrt{(x_1 - x_2)^{2} + (y_1 - y_2)^{2}}$

$\bigstar \: \sqrt{(0 - a)^{2} + (0 - 2a)^{2}}$

$\bigstar \sqrt{( - a)^{2} + ( - 2a)^{2}}$

$\bigstar \sqrt{a^{2} + 4a^{2}}$

$\bigstar \sqrt{5a^{2}}$

$\bigstar \: a \sqrt{5}$
