Common geometry formulas
Here, we provide you with common geometry formulas for some basic shapes
Rectangle:
Perimeter = l + l + w + w = 2 × l + 2 × w
Area = l × w
Square:
Perimeter = s + s + s + s = 4 × s
Area = s^{2}
Parallelogram:
Perimeter = a + a + b + b = 2 × a + 2 × b
Area = b × h
Rhombus:
Perimeter = b + b + b + b = 4 × b
Area = b × h
Triangle:
Perimeter = a + b + c
Area = (b × h)/2
Trapezoid:
Perimeter = a + b + c + d
Circle:
Perimeter = 2 × pi × r or Perimeter = pi × d
Area = pi × r
^{2} or Area = (pi × d
^{2})/4
