**Area of Rectangle**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).

**A=hxbb/2****Area of Triangle**Insert the values for all the three edges of the triangle.

**Area of Trapezoid**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**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.

**Area of Sector**Input the radius and the degree of angle of the sector.

**Area of Ellipse**To calculate the area of ellipse, you just need to mention the length of the major and minor axes in this Area Calculator.

**Area of Parallelogram**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 heightSquare Area = a ^{2}a = length of sideRectangle Area = w Ч h w = width

h = heightParallelogram Area = b Ч h b = base

h = vertical heightTrapezoid (US)

Trapezium (UK) Area = Ѕ(a+b) Ч h h = vertical heightCircle Area = ? Ч r ^{2}Circumference = 2 Ч ? Ч r

r = radiusEllipse Area = ?ab Sector Area = Ѕ Ч r ^{2}Ч ? r = radius

? = angle in**radians**- Note:
**h**is at right angles to**b:**
