Answer 2

Ello There!

--------------------------

We know that area of a paralellogram = base × height

Since we have a pair of base AB and height DE, lets calculate the area of ABCD first.

ar(ABCD) = AB × DE

ar(ABCD) = 25  × 10

ar(ABCD) = 250m²

Now we have found out the area of ABCD.

We can see that we see another pair of base BC (the adjacent side we need to find) and an altitude DF.

Therefore we have another equation

ar(ABCD) = base × height

ar(ABCD) = BC × DF

       250 = BC × 20

        = BC

       12.5 = BC

∴ The value of the Adjacent side is 12.5cm
