a cyclist travel a distance of 4km from P to Q then moves the distance of 3km at right angle to PQ. find its resultant displacement graphically?

1. Using graph paper, draw a 4inch line from the origin parallel to the positive xaxis.
2. Draw a 3inch vertical line from the
origin parallel to the positive yaxis.
3. Complete the rectangle with the hor.
sides 4 inches long and the ver sides 3 inches long.
4.Draw a diagonal from the origin to the upper right hand corner of the rectangle. This is the resultant.
5. Measure the length of the resultant;
it should be approximately 5 inches.
