Web18 de dic. de 2024 · To find the area of a trapezoid ( A ), follow these steps: Find the length of each base ( a and b ). Find the trapezoid's height ( h ). Substitute these values into the trapezoid area formula: A = (a + b) × h / 2. You can notice that for a trapezoid with a = b (and hence c = d = h), the formula gets simplified to A = a × h, which is exactly ... WebA sector of a circle is essentially a proportion of the circle that is enclosed by two radii and an arc. Given a radius and an angle, the area of a sector can be calculated by multiplying the area of the entire circle by a ratio of the known angle to 360° or 2π radians, as shown in the following equation: area =. θ. 360.
