Additionally, learn to find the apothem using the perimeter, radius, side lengths or areas as well. Use the appropriate area formula to find the area of each shape, add the areas to find the area of the irregular polygons. In this worksheet, we will practice finding areas of regular polygons given their side lengths using a formula. Find the area of the regular polygon by substituting the circumradius and the number of sides in the area formula. Find the perimeter, rearrange the area formula, making apothem the subject, plug in the values of the perimeter and area to determine the apothem. The following diagram gives the formula to find the area of a regular polygon using the perimeter and the apothem. Problem solver below to practice various math topics. This worksheet is a great resources for the 5th, 6th, 7th and 8th Grade.

Since one side is half of a diagonal, the area of a rhombus formula is one half the product of the diagonals. Quickly add and underline text, insert pictures, checkmarks, and symbols, drop new fillable areas, and rearrange or remove pages from your document. The area formula for a kite is found by rearranging the pieces formed by the diagonals into a rectangle. Find the area giving the answer to two decimal places.
If radii are drawn from the center of a regular polygon to the vertices, congruent isosceles triangles are formed. Also included in: Geometry MEGA BUNDLE - Foldables, Activities, Anchor Charts, HW, & More. An apothem is a perpendicular segment from the center of a regular polygon to one of the sides. Click here if you would like a Area and Perimeter Formula handout for your students. You may select from pentagons, hexagons, heptagons, octagons, nonagons, decagons, hendecagons, and dodecagons. Edit Regular polygons worksheet pdf. This video shows you how to use a formula to find the area of any regular polygon. Level up with this batch of high school worksheets on finding the apothem.
An additional formula for the area of a rhombus is to use the kite formula (it works because rhombuses are technically kites). Try the given examples, or type in your own.
