Q1 of 16 Page 149

Draw a parallelogra of sides 5 centimetres, 6 centimetres and area 25 square centimetres and area 25 square centimetres.

Area of the parallelogram:

The product of base of the parallelogram and the height of the parallelogram.



area of the parallelogram = base × height


= b × h


Given that


Sides of the parallelogram are 5cm & 6cm


Area of the parallelogram = 25 cm2


We can write that as


Area = 5 cm × 5 cm


That means base of the parallelogram (b) = 5 cm


height of the parallelogram (h) = 5 cm


With height and base and side we will draw a parallelogram.



We need to find the value of X


In the above fig. triangle AOD is a right- angled triangle with AD as hypotenuse.


AD2 = A02 + OD2


62 = X2 + 52


X2 = 36 – 25


X = √9


X = 3 cm


Using height, sides & X we can draw the parallelogram.
