Insert the values of length and edge of the rectangle and choose the unit you used to measure those. Area of a rectangle is calculated as: (length x edge).
Insert the values for all the three edges of the triangle.
To calculate the area of trapezoid, mention the top edge, bottom edge, and height of the trapezoid. The area of trapezoid is calculated as: Ѕ(top edge + bottom edge) x height.
Area of circle is measured as: ?r2; where r is the radius and ? = 3.1416. You need to input the radius of the circle only to find out the area of the circle.
Input the radius and the degree of angle of the sector.
To calculate the area of ellipse, you just need to mention the length of the major and minor axes in this Area Calculator.
Insert the length of the base and the height of the parallelogram you want to calculate the area for. The area of parallelogram is calculated as: (base x height).
Triangle Area = Ѕ Ч b Ч h b = base h = vertical height | Square Area = a^{2} a = length of side | |||
