Area is the size of a surface! Learn more about Area, or try the Area Calculator. Triangle. Area = ½ × b × h. b = base. h = vertical height. Square. Area = a2. a = length of side.
Area formula. The area of a two dimensional shape or geometric figure is the space contained within its perimeter. Area formulas of common shapes. The exact area of many common shapes can be calculated using well-defined formulas. Circle. The area of a circle with radius r is: A = πr 2. Triangle.
Area is measured in "square" units. The area of a figure is the number of squares required to cover it completely, like tiles on a floor. Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared.
Here are the most important and useful area formulas for sixteen geometric shapes: Square area formula: A = a². Rectangle area formula: A = a × b. Triangle area formulas: A = b × h / 2 or. A = 0.5 × a × b × sin(γ) or. A = 0.25 × √( (a + b + c) × (-a + b + c) × (a - b + c) × (a + b - c) ) or.
Find the area of shapes in Maths here. Learn the formulas for the area of different types of plane figures and solid shapes along with the table and solved examples at BYJU'S.
Surface Area Formulas. Variables: \(SA\) = Surface Area \(B\) = area of the base of the figure \(P\) = perimeter of the base of the figure \(h\) = height \(s\) = slant height \(r\) = radius
The formula is: Area = w × h. w = width. h = height. The width is 5, and the height is 3, so we know w = 5 and h = 3: Area = 5 × 3 = 15. Learn more at Area of Plane Shapes.
