Question

5. Find the base of a parallelogram, which
has an area of 840 cm2 and normal on
base is 21 cm.​

Answer 1

Given:-

• Area of the parallelogram is 840 cm².
• Height of the parallelogram is 21cm .

To Find:-

• The base of the parallelogram.

Solution:-

We know that the area of parallelogram is

$\boxed{\red{\sf Area_{llgm}=base\times height }}$

=> Area = b*h

=> 840 cm² = b * 21cm

=> b = 840cm²/21cm.

=> b = 40cm.

Hence the base of parallelogram is 40 cm.
