Identify parallel and perpendicular lines
Nana76 [90]

Parallel lines are those on a plane that do not intersect while perpendicular lines are those that intersect at an angle of 90°.

<h3 /><h3>How are parallel and perpendicular lines different?</h3>

Parallel lines will never intersect with each other and will maintain the same distance from each other for as long as they are on the same plane.

Perpendicular lines on the other hand will intersect each other and will do so at a 90° angle. An example of such a line is the steps on a ladder which intersect the beam at a 90° angle.

When calculating the area of the rectangular wall, we have to multiply 16.5ft(8.625ft), if we observe, we have 4 decimals in total. The multiplications results 142.3125. So, Cameron solution is not reasonable, because he only included three decimals points, instead of four.

16.5ft(8.625ft)=142.3125ft^{2}
