7th Maths : Term 1 Unit 2 : Measurements : Summary

**Summary**

● Parallelogram is a four sided closed shape in
which opposite sides are both parallel and equal.

● Area of the Parallelogram = *b* × *h
sq. units*, where *b* = base ; *h* = height.

● In a parallelogram if all the sides are equal
then it is called Rhombus.

● Area of rhombus = 1/2 × *d*_{1} ×
*d*_{2} *sq. units*, where *d*_{1}, *d*_{2}
are the diagonals.

● A parallelogram with one pair of non-parallel
sides is known as a Trapezium.

● Area of Trapezium = 1/2 × *h*(*a*+*b*) *sq. units*

● If the non - parallel sides of a Trapezium
are equal then it is known as an isosceles Trapezium.
