I don't think you are giving quite enough information. Are you taking a test? This came from a book or test. If the parallelogram is a rectangle, the base is 16. Is the figure a rectangle?
Area of a parallelogram in square units = base*height
Height of parallelogram: 245/14 = 17.5 inches
280/20 = 14 units in length
14
The base can be any non-negative number, with the height then being 40/base.
Area of a parallelogram in square units = length*perpendicular height
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.
Base * Vertical distance between bases (height).
Area of a parallelogram in square units = base*height
There is no triangle below. But, given that area = 224 sq units and height = 14 units, then base = 224/14 = 16 units.
15 units
240 square units
Area of a parallelogram = base * height = 6.5 * 1.5 = 9.75 square units.
Height of parallelogram: 245/14 = 17.5 inches
Area = Base*Height = 15*12.3 = 184.5 square units.
It is: 5015/59 = a base length of 85 units
