The parallelogram shown below has an area of 35 units^2

35 units = 7 x 5units

This means the height is 5 units

Area = 35units^2

Step-by-step explanation:

We can check in number of ways to assure the area is correct and the heights match the line h has created a secondary height of a trapezoid 4.7 + 7 = 11.7 x 6 = 70 x 1/2 = 35 area

To match with

7 x 5 = 35 area.

So we can see the first triangle measures 6, 5 and 2.3

As 2.3 + 4.7 = 7 units on the given parallel base line.
