Hey!
Hope this Helps....

To find the perpendicular line, of any given line goes like this...
if m (slope) of this given line is 1/3, than we know that the perpendicular line has a slope of -3
Now, to find the equation of this line, we need to find out where it crosses the y-axis... And because we are not given any specific points on where the perpendicular line crosses. We see that the point it pass the y-axis is 0
So... the perpendicular line of 1/3x+2 is -3x
Area is 74 in/cm/mm^2 hope this helps :)
If P=360, then 360yd / 4 sides = 90yds each side. Now that it is a rectangle, the Length should be more than the width, so if the length is 20yds more than the width, do 90 - 20 two times, Width= [ (90yds - 20yds)*2 ]
To sum things up, Length = 110; Width = 70. | 110*2 = 220, 70 * 2 = 140, 220+140 = 360.
