Answer:

Therefore the area of parallelogram  is 32 cm².

Step-by-step explanation:

Given:

[] ABCD is a Parallelogram .........Given

AB = 4 cm = Base

BC = 10 cm

CE  = Height of Parallelogram  

To Find:

area of parallelogram  = ?

Solution:

In Right angle triangle BEC  by Pythagoras theorem we have

[tex](\textrm{Hypotenuse})^{2} = (\textrm{Shorter leg})^{2}+(\textrm{Longer leg})^{2}[/tex]

Substituting the values we get

[tex]10^{2}=6^{2} +CE^{2} \\\\CE^{2}=100-36=64\\ \\\therefore CE = 8\ cm\\[/tex]

Which is the Height of Parallelogram

Now, area of parallelogram  given by

[tex]\textrm{Area of Parallelogram} = Base\times Height[/tex]

Substituting the values we get

[tex]\textrm{Area of Parallelogram} = 4\times 8=32[/tex]

[tex]\textrm{Area of Parallelogram} = 32\ cm^{2}[/tex]

Therefore the area of parallelogram  is 32 cm².
