$A=(14,-6)\qquad B=(-4,7)\\\\\\\bold{u}=\overrightarrow{AB} =\left\ \textless \ -4-14,7-(-6)\right\ \textgreater \ =\left\ \textless \ -18,13\right\ \textgreater \ \\\\\\
||\bold{u}||=\sqrt{(-18)^2+13^2}=\sqrt{324+169}=\sqrt{493}\approx22,2$

A square has a side of 8cm. The area of the square increases by 50%. Work out the percentage increase in the length of the side.

sertanlavr [38]

Because the side has to be increased by 50%
you find half of 8, which is 4 and you add 8+4 because you add the increased amount
8+4=12
you then just find the area.... so 12x12= 144
