In obtaining the scale factor of PQRS to JKLM, try to look for side lengths given in the figure. They can be expressed as fractions or decimals. The perimeter of any polygon is the total distance around the outside, which can be found by adding together the length of each side. From there, express the area of the smaller polygon in terms of the larger polygon. On calculators with Slider Controls, drag slider tab to get close, then use keyboard cursor keys to fine tune. Now that we have obtained the value of the shorter side create a proportion formula for the side lengths and corresponding segments such as medians and angle bisectors. Two quadrilaterals are similar quadrilaterals when the three corresponding angles are the same( the fourth angles automatically become the same as the interior angle sum is 360 degrees), and two adjacent sides have equal ratios. A = (1/4) na2cot (/n) = (1/4) 7 62cot (3.1415/7), A = (1/4) 252 cot (0.4488) = (1/4) 252 2.07. Whereas, similar polygons have the same shape, but not the same size (i.e., one is bigger than the other). This is illustrated in more depth in "Similar Triangles", but is true for all similar polygons, not just triangles. The area of the smaller polygon is equal to As = 48 cm2. The inputs above will be hidden when the program finally gets launched. Take note that the given length of the side of the smaller polygon SS is 3 centimeters. Total Area 45.25 ft.
