Calculate Parallelogram Height AE Using Area = 40 cm² and Base = 8 units

Look at the parallelogram in the figure below.

Its area is equal to 40 cm².

Calculate AE.

We are told that ABCD is a parallelogram,$AB=CD=8$According to the properties of a parallelogram, each pair of opposite sides are equal and parallel.

Hence to find AE we will need to use the area given to us in the formula in order to determine the area of the parallelogram:

$S=DC\times AE$

$40=8\times AE$

We divide both sides of the equation by 8:

$8AE:8=40:8$

$AE=5$
