Q2 of 16 Page 149

Draw a parallelogram of area 25 square centimetres and perimeter 24 centimetres.

Given

Area = 25 cm2


Area = 5 cm × 5 cm


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


height of the parallelogram (h) = 5 cm


Perimeter = 24 cm


2 (A + B) = 24 cm


A + B = 12 cm


where A & B are sides of a parallelogram


since base is also a side of a parallelogram.


B = 7 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 POS is a right- angled triangle with PS as hypotenuse.


PS2 = PO2 + OS2


72 = X2 + 52


X = √(49-25)


= √24


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