Explanation:
"since O is the origin the equation will be in the form"
•color(white)(x)y=mx
"where m is the slope"
m=(Deltay)/(Deltax)=22.5/10=22.5/10=2.25
rArry=2.25x" is the equation of line"
OA=sqrt(10^2+22.5^2)larrcolor(blue)"Pythagoras' theorem"
color(white)(OA)~~24.6221.." Km
color(white)(OA)=24.622" Km to nearest metre"
