The height of the parallelogram is 6.4 m.
<h3>What is a parallelogram?</h3>
A parallelogram is a quadrilateral. Let us recall that a quadrilateral is a four sided figure. It is also important to recall that the opposite sides of a parallelogram are equal.
Let us now try to find the height of the parallelogram;
Given that;
/DE/ = /AC/
10 = /BC/ + /AB/
/AB/ = 10 - /BC/
/AB/ = 10 - 6
/AB/ = 4 cm
Then;
/AE/= /CD/ = 5 cm
Using the Pythagoras theorem;
/EB/^2 = /AE/^2 + /AB/^2
/EB/ = √/AE/^2 + /AB/^2
/EB/ = √(5)^2 + (4)^2
/EB/ = √ 25 + 16
/EB/ = 6.4 m
