Irregular polygons are polygons that do not have equal sides or equal angles. When finding the area of an irregular polygon, partition the polygon into smaller regular polygon shapes. You can then plug those measurements into their respective area formulas and multiply to find the area of one part of the shape.

To find the area of a rectangle, you need two measurements: the width, or base (the longer side of the rectangle), and the length, or height (the shorter side of the rectangle). Then, just multiply them together to get the area. In other words: Area = base × height, or A = b × h for short.

The formula for the lateral surface area of a rectangular box, also called a cuboid, is 2h(l + w), where l = length, w = width, and h = height.

To find the surface area of an irregular hexagonal prism, we just add up the areas of the bases and faces of the prism. To find the surface area of a regular hexagonal prism, we can use the formula SA = 6s(a + h), where s = side length of the base, a = apothem length, and h = height of the prism.

Using the length and width you just measured, plug them into the formula to solve for the area. Multiply the length times the width to calculate area. For example, A = l x w = 5 x 2 = 10 cm2.

The area of any irregular quadrilateral can be calculated by dividing it into triangles. Example: Find the area of a quadrilateral ABCD whose sides are 9 m, 40 m, 28 m and 15 m respectively and the angle between the first two sides is a right angle. The area of the quadrilateral ABCD =(180+126)=306 square meters.

To find the area of irregular shapes, the first thing to do is to divide the irregular shape into regular shapes that you can recognize such as triangles, rectangles, circles, squares and so forth... Then, find the area of these individual shapes and add them up!

To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.

A trapezoid will have two sides parallel. Add the lengths of these parallel side, find its average and multiply this average length by the distance between these lines and you get the area.

For squares, multiply one side by itself to get the area. If you have a parallelogram, multiply the diagonals and divide by 2 to get the area. To find the area of a trapezoid, add the base and the height together, and divide that number by 2 times the height.

The measure of the interior angles of a regular polygon is given by the formula: 180(n - 2) / n degrees, where n is the number of sides of the polygon while the measure of the exterior angles of a regular polygon is given by the formula: 360 / n degrees, where n is the number of sides of the polygon.

In the case of a circle, the formula for area, A, is A = pi * r^2, where r is the circle's radius. Since we know that a semicircle is half of a circle, we can simply divide that equation by two to calculate the area of a semicircle. So, the formula for the area of a semicircle is A = pi * r^2/2.

The area of any regular polygon is given by the formula: Area = (a x p)/2, where a is the length of the apothem and p is the perimeter of the polygon.

The distance around a polygon is called the perimeter. To find the perimeter of any polygon you add the lengths of its sides. For example the perimeter of the irregular polygon below is 12 units.
