Find the area of each regular polygon. Round to the nearest tenth. (a) an equilateral triangle with an apothem 8.9 inches long. (b) a pentagon with an apothem 0.4 feet long Find the area of the triangle in the below figure.
√ EXAMPLE 2 Find the area of a regular polygon STEP 2 Find the apothem a. The apothem is height RS of ∆PQR. Because ∆PQR is isosceles, altitude RS bisects QP . So, QS = (QP) = (15) = 7.5 inches. 1 2 To find RS, use the Pythagorean Theorem for ∆ RQS. a = RS ...

Finally, multiply the length and width.10* 12=120The area of the polygon is 120 square units.In this case, the area can also be found by counting the squares enclosed by the polygon. There are 30 squares.How much area is represented by each square? 2* 2, or 4 square units.The ...
If a polvaon is made up of more than one rectanale, you can find its area by following the steps in the flowchart below.Step 1: Separate the polygon into rectangles.↓Step 2: Label the length and width of each rectangle.↓Step 3: Find the area of each rectangle....
To find the area of the given polygon, we will break the polygon down into simpler shapes: triangles and trapeziums. We will calculate the area of each shape and then sum them up to find the total area. 1. Identify the Shapes: - The polygon consists of 4 triangles and 2 trapeziums...
Find the perimeter and area of the polygon with the given vertices. J(−4,1),K(−4,−2),L(6,−2),M(6,1) Rectangles A rectangle is simply any polygon that contains four right angles. In the plane, we can check that a polygon is a rectangle if ...
Help please, I want to find out the Centroid, the Area and the Moment of Inertia of any polygon, from an axis line drawn under that shape. Then how to make a GUI program that displays a two-dimensional area shape along with its centroid marked on the...
