Know the correct formula. 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.

To find the width of a rectangle, use the formula: area = length × width. Just plug the area and length of the rectangle into the formula and solve for the width. If you don't have the area, you can use the rectangle's perimeter instead. In that case, you would use the formula: perimeter = 2 × length plus 2 × width.

Area is measured in square units. The area of the rectangle can be calculated using the following formula: A = l   w, where l represents the length and w represents the width. Perimeter is the length of the boundary of the shape. It can be calculated adding the measurements of each side.

When two-dimensional figures are shown on the coordinate plane, a mix of counting and the Pythagorean Theorem can be used to determine the lengths of each side. Then add up the lengths to determine the perimeter or use the basic area formulas for triangles and rectangles to determine the area of the figure.

To find the area of an irregular polygon you must first separate the shape into regular polygons, or plane shapes. You then use the regular polygon area formulas to find the area of each of those polygons. The last step is to add all those areas together to get the total area of the irregular polygon.

Determining the Area of the Heptagon The formula for this is Area=(1/2)nsr. In this case, “n” is the number of sides, “s” is the length of the sides, and “r” is the apothem. Using the same example above, with the side as 7, the area formula would be worked as follows: Area=(1/2)(7)(7)(7.268).

Since there are as many of these triangles as the polygon has sides (eight for an octagon), you have to multiply the area of this triangle by the number of sides. You will obtain the total area of the octagon: area of octagon = 8 * base * height / 2 = perimeter * apothem / 2 .

All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides. The sum of exterior angles of a polygon is 360°.

You also learned the formula for finding the area of any regular polygon if you know the length of one side and the apothem: A = (n × s × a)2 A = ( n × s × a ) 2 , where n is the number of sides, s is the length of one side, and a is the apothem.

The perimeter is 16 cm. In a plane, a simple closed polygon encloses a region that can be assigned a number called the area. The area of a region can be thought of as the number of square units, or parts of square units, that are required to cover the region without overlap.

Correct answer: To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides.

To find the perimeter of a regular hexagon you must first know the number of sides in a hexagon which is 6. When you know the number of sides of a regular polygon to find the perimeter you must multiply the side length by the number of sides. The answer for the perimeter is .

For the circular cylinder there are the following formulas: The perimeter p is 2·Pi·r (this is the formula for the perimeter of the circle), the base area AB is Pi·r² (this is the formula for the area of a circle), the lateral surface is perimeter times height, AL = p·h and therefore AL = 2·Pi·r·h, the surface area ...
