Question

In parallelogram ABCD, AB = 12 cm. The altitudes corresponding to the sides AB and AD are respectively 9 cm and 11 cm. Find AD

Answer 1

Answer:

The length of the side AD is 12 cm

Step-by-step explanation:

In the given questions,

                             $AB=12cm\\ \\ DM=5\\ \\ AD=8cm$

we know that,

           Area of parallelogram= b × h Square units

            Where “b” is the base and “h” is the height of the parallelogram.

 Area of parallelogram $=b \cdot h=12 \cdot 8=96$

Again take $h=8cm$

Area of parallelogram $=b \cdot 8$

                                 $96= 8 \cdot b\\ \\ 8b=96\\ \\ b=\frac{96}{8}=12$
