FORMULAS FOR SHAPES
About the topic formulas for shapes
In this page formulas for shapes you can find many shapes and related formulas.Mensuration is one of the branches of mathematics.This means measurement.It is is being done in our life in many situations.
For example,
For example,
A length of cloth we need for stitching, the area of a wall which is being painted, perimeter of the circular garden to be fenced. For these kind of situation we need to use one of these formulas. Here, we cover two major areas.
1. Perimeter
2. Area
Name of shape | Formulas |
Circle
| |
Area of circle = Π r ²
Circumference of circle = 2 Π r
| |
Equilateral Triangle
| |
Area of Equilateral-triangle = (√3/4) a²
Perimeter of Equilateral-triangle = 3a
| |
Scalene Triangle
| |
Area of scalene triangle = √s(s-a)(s-b)(s-c)
Perimeter of scalene triangle
= a + b + c
| |
Semi circle
| |
Area of Semi circle= (1/2) Π r²
Perimeter of semi-circle = Πr
| |
Quadrant
| |
Area of quadrant = (1/4) Π r²
| |
Parallelogram
| |
Area of parallelogram = b x h
| |
Quadrilateal
| |
Area of quadrilateral
=(1/2) x d x (h₁+h₂)
| |
Rectangle
| |
Area of rectangle = L x W
Perimeter of rectangle=2(l+w)
| |
Square
| |
Area of square = a²
Perimeter of square = 4a
| |
Rhombus
| |
Area of rhombus =(1/2) x (d₁ x d₂)
