Question

3. Find the area of the given parallelogram ABCD and hence the altitude on BC.​

Answer 1

Answer:

The area of the parallelogram is 115.2 cm² and the height/altitude is 9.6cm.

Step-by-step explanation:

To find the area of parallelogram ABCD, we have to know the base and the altitude. since we got AB as base and the corresponding altitude as MN, we can see that:

area of parallelogram=bh

∴ area of ABCD= 18* 6.4

= 115.2cm²

Now to find the altitude on BC, we need the area of ABCD and the base(BC). We got base as 12cm and area as 115.2cm²

Now we know that area of parallelogram=bh

∴ h= area of parallelogram/b

= 115.2/12

= 9.6cm
