PARALLELOGRAM

OPPOSITE SIDES ARE EQUAL AND PARALLEL,

ADJACENT SIDES DO NOT MAKE RIGHT ANGLES.THIS
GEOMETRICAL SHAPE IS CALLED PARALLELOGRAM.

Area of the Parallelogram = Base x height sq.units

Perimeter of the Parallelogram = Sum of the length
of the four sides

= 2(a+b) units

PARALLELOGRAM IN REAL LIFE

1. The base of the parallelogram is thrice its height. If
the area is 192 sq. cm, find the base and height.

2. Find the perimeter of a parallelogram whose
adjacent sides are 6 cm and 5 cm.

EXERCISES

1. Find a real life objects shaped as Parallelogram. And

measure their base, height and sides and find out the
area and perimeter of that object.

2. Imagine You won a parallelogram-shaped trophy in a state

level Chess tournament. He knows that the area of the
trophy is 735 sq. cm and its base is 21 cm. What is the
height of that trophy?
