1 Circle – Formulas

2 Quadrilaterals – Formulas Square Area = s 2 Perimeter = 4s (s = side) Rectangle Area = lb Perimeter = 2(l+b) l = length b = breadth Area = (d1d2)/2 Perimeter = 4s s = side d1,d2 = diagonals Rhombus Area = ba Perimeter = 2(l + b) (b = base/breadth a = altitude l = length) Parallelogram Trapezium Kite d1, d2 = diagonals

3 Triangles – Formulas Perimeter of an equilateral triangle = 3s (s = side) Area of an equilateral triangle Area of a triangle = ½ × base × height

4 Solids – Formulas
