Common geometry formulas 


Here, we provide you with common geometry formulas for some basic shapes





Rectangle:


Rectangle
Perimeter = l + l + w + w = 2 × l + 2 × w

Area = l × w



Square:


Perimeter = s + s + s + s = 4 × s

Area = s2





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 × r2 or Area = (pi × d2)/4
