Polygon maths formula
WebSep 19, 2024 · The area of a regular polygon is one-half the product of its apothem and its perimeter, i.e., Area = 1 2 × a × p, where a is the length of an apothem, and p is the perimeter. Therefore, formula for area of a regular polygon is Area = 1 2 × s 2 tan θ 2 × p. Therefore, Area = 1 2 × s 2 tan θ 2 × n × s = n s 2 4 tan θ 2. WebMar 24, 2024 · Polygon Area.

WebThe formula to calculate the area of a trapezoid is: A = (b1 + b2) * h / 2. Where b1 and b2 are the lengths of the two parallel bases of the trapezoid, and h is the perpendicular distance between the bases. Substituting the given values, we get: A = (7 + 11) * 5 / 2. A = 18 * 2.5. A = 45 square inches. Therefore, the area of the trapezoid is 45 ...
