Common geometry formulasHere, 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 Related topics: Volume formulas Surface area formula Buy a comprehensive geometric formulas ebook. All geometric formulas are explained with well selected word problems
