A regular nonagon with a side length of 9 has an apothem of 12.4 not 16. So the question is inconsistent.
To find the area of a triangle, you can use the formula: Area = 0.5 * base * height. In this case, the base is 8cm and the height is 4cm. Plugging these values into the formula, the area would be 0.5 * 8cm * 4cm = 16 square centimeters.
55.6 cm^2 approx.
The apothem and side length are not consistent. That is, a nonagon with an apothem of 5.6 cm cannot have a side length of 4.1 cm.If the apothem is 5.6 cm then area = 102.7 cm2 whileif the side length is 4.1 cm then area = 103.9 cm2.The two answers agree at the tens place and so the most accurate answer is 100 cm2 to the nearest 10.
a nine sided polygon is called a nonagon.
A square with a side length of 4cm has an area of 16cm2
Yes (apart from units):If the side of a square is 4cm then itsperimeter is 4cm + 4cm + 4cm + 4cm = 4 x 4cm = 16cm;area is 4cm x 4cm = 16cm2
96 cm.^2
The area is about 41.57cm2
The area is indeterminate, since the shape can be a long thin nonagon with minimum area or a regular one with maximum area.
Each side is 2cm
4cm

to work out the area of a sqaure it is the length of the side multiplied by another side. seing as the sides of a sqaure are all equal, is is the side of a square multiplied by itself. for example if the side of a square was 4cm the equation would be: 4cm x 4cm = 16cm^2 do not get this equation confused with the equation for a rectangle which is length multiplied by the width. (L x W)
Area = (side)2 = 16 square centimeters Perimeter = 4 x side = 16 centimeters
