Question

a triangle and a parallelogram is 10 centimetre find the altitude of the triangle​

Answer 1

Answer:

7.5 is the altitude

Step-by-step explanation:

The given figure ABCD is a parallelogram with AO is the altitude corresponding to the side CD and CP is the altitude corresponding to side AD.

⇒  The given sides of the parallelogram are 10cm and 15cm.  

So, take AD = 10cm, CD = 15cm and AO = 5cm.  

We have to find length of CP.

⇒  Area of a parallelogram with with base AB and altitude AO is,

∴  Area of parallelogram ABCD=AB×AO

⇒15×5  -- (substituting values)

∴  Area of parallelogram =75 cm  

⇒  Area of parallelogram ABCD with base AD and altitude CP, as area will remain same.

∴ Area of parallelogram ABCD=AD×CD

⇒75=10×CD

∴CD=7.5cm

We get 7.5 is the altitude to the side of length 10cm.
