Question 1134296: ABCD is a parallologram and line AM and line AN are perpendiculers from A to line BC and CD respectively. If AB = 6.3cm, AD = 4.9cm and AN = 4.2cm, calculate the area of the parallelogram and hence find AM.

The area of the parallelogram is base times height; you can use either pair of sides for the base. So in your parallelogram, since BC and AD are the same length, the area is

(AB)*(AN) = (AD)*(AM)

Use the expression on the left to calculate the area; then use the area with the expression on the right to determine the length of AM.
