280/20 = 14 units in length

It has a perimeter of 12 units, an area of 7 (6.9282) square units and an altitude of 3.5 (3.4641) units.
Area of a parallelogram in square units = base*height
It is possible, but it all depends on what they are lengths of!
Using Pythagoras' theorem it works out as 10.5 units of measurement

Area of a parallelogram in square units = length*perpendicular height
It is double the length of the base, in square units.
It has a perimeter of 12 units, an area of 7 (6.9282) square units and an altitude of 3.5 (3.4641) units.
To find the height of a parallelogram, you divide the area by the base length. So in this case, the height of the parallelogram would be 115/12 = 9.58 to the nearest hundredth.
How can we answer when we can't see the diagram... ----------------------------------------------------------------------------------------- ok heres the address to look at the diagram. http://media.apexlearning.com/Images/200706/08/23acc479-434a-4776-998e-d4d7dae81fe2.GIF PLEASE NEED THE ANSWER!!!! ---------------------------------------------------------------- The altitude is 20: Apex test =]
