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. If a square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches. Some formulas for common -dimensional plane figures and -dimensional solids are given below. The answers have one, two, or three dimensions; perimeter is measured in linear units, area is measured in square units, and volume is measured in cubic units. s is the length of the side of the square. Area and Volume Formula for geometrical figures - square, rectangle, triangle, polygon, circle, ellipse, trapezoid, cube, sphere, cylinder and cone.
The most basic area formula is the formula for the area of a rectangle. Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. Formal definition - Units - History - Area formulas. Areas. square = a2. rectangle = ab. parallelogram = bh. trapezoid = h/2 (b1 + b2). circle = pi r 2 [s(s-a)(s-b)(s-c)] when s = (a+b+c)/2 (Heron's formula). Learn how to calculate the area of common shapes for real life situations. Area can be calculated using simple formulas, depending on the type of shape you.
