Mensuration Formula For 2D Shapes
The following table provides a list of all mensuration formulas for 2D shapes:
| Shape | Area (Square units) | Perimeter (units) | Figure |
|---|---|---|---|
| Square | a2 | 4a | Square dimensions |
| Rectangle | l × b | 2 (l + b) | rectangle dimensions |
| Circle | πr2 | 2 π r | circle with radius |
| Scalene Triangle | √[s(s−a)(s−b)(s−c)], Where, s = (a+b+c)/2 |
a+b+c | Scalene triangle dimensions |
| Isosceles Triangle | ½ × b × h | 2a + b | isosceles triangle dimensions |
| Equilateral Triangle | (√3/4) × a2 | 3a | Equilateral triangle dimensions |
| Right Angle Triangle | ½ × b × h | Right Angle Triangle dimensions |
|
| Rhombus | ½ × d1 × d2 | 4 × side | |
| Parallelograms | b × h | 2(l+b) | Parallelogram dimensions |
| Trapezium | ½ h(a+c) | a+b+c+d | Trapezium dimensions |
