AREAS OF PLANE FIGURES

TRIANGLE :- It is a closed figure bounded by three line segments it has 3 corners. 1. 2.

Area of a Tringle= ½ (base)(height) (when its base and height are given) S = (a+b+c)/2

(Hero’s Formula)

PARALLELOGRAM = It is a quadric lateral having two pair of opposite sides parallel and equal . .Area of Parallelogram = base*height

RHOMBUS =It is a quadric lateral having all the four sides equal and parallel . Its diagonal are perpendicular bisectors of each other .

Area of Rhombus= ½*d1*d2

RECTANGLE= It is a parallelogram having all the angles equal to 900 and opposite sides are equal and parallel.

Area of Rectangle=Length*breadth

SQUARE= Its all sides equal , its diagonal are equal and bisect each other at 900 and all angles are 900

Area of Square=Side*Side Submitted by:
