Calculate The Area of Common Shapes

Calculate the area of square, circle, triangle, equilateral triangle, Parallelogram, Trapezium or Sector.

Area of square: [ (side)² ] Enter the length = Result Area =

Circle: Enter the diameter = OR Enter the radius = Result Area [ || r² ] = Result Circumference [ 2|| r ] =

Area of triangle: [ l×b/2 ] Enter the length and breath = Result Area =

Area of Equilateral Triangle: [ (Sqrt(3)/4)*(side)² ] Enter the length = Result Area =

Area of Parallelogram or Rectangle: [ base×height ] Enter the lengths = Result Area =

Area of Trapezium: [ ½×(sum of parallel sides)×(distance between them) ] Enter the size of parallel side 1 = Enter the size of parallel side 2 = Enter the distance between parallel sides= Result Area =

Area of Sector: [ ½×arc×(angle in degree) ] Enter the radius = Enter the angle = Result Area =
