The area of the trapezoid is calculated by using the formula - (b1 + b2)/2Xh. The two sides that are parallel are called the bases of the trapezoid and the other sides that are not parallel are called the legs. The formula is written as:Īrea = vs(s-l)(s-m)(s-n), here s is the semi perimeter and l, m, n are the three sides of the triangle.Ī quadrilateral that has one pair of parallel sides and two other sides that are not parallel is called a trapezoid. The most commonly used one for calculating the area of a triangle is Heron's formula or the Hero's formula, named after the famous Greek mathematician and engineer, Hero of Alexandria. The area calculator helps you to calculate the area of all types of triangles. This is one of the most commonly used formulas particularly in building construction, wall painting and floor tiling. The equation for calculating the area of a rectangle is - area = length X width. In the case of a square, all the sides are equal, whereas in a rectangle two sides are equal, the two longer sides are called the length and the two smaller sides are called the width. Let us look at how you can calculate the area of some commonly used shapes.īoth square and rectangles are quadrilaterals with four right angles. An area is also measured in these units - hectare, square foot, square yard, acre and square mile. The SI unit of area is the square metre and it is denoted by m2 other units that are commonly used for calculating an area are square centimetre, cm2 and square kilometre, km2. Area of complex shapes can be calculated by breaking them down into simple shapes and then summing up their respective areas. The Area Calculator helps you to calculate the area of each shape, for instance, if you own a piece of land, you can calculate its area by using the formula. The area is the size of a surface that can be calculated using formulas associated with each surface or shape.
