The ratio is 10:14 or 5:7 which is the ratio of boys to girls!
My friend is obviously wrong. If I'm paying $2.40 for three fourths of a pound, what makes him think that he'll pay less for more grapes? This equation actually doesn't involve any equations.
The area of regular polygon with 5 sides is 689.65m²
<u>Explanation:</u>
All sides of a regular polygon are equal in length. If you know the length of one of the sides, the area is given by the formula:
where
s is the length of any side
n is the number of sides
tan is the tangent function calculated in degrees
Let the number of side of a polygon be 5. So, putting the values in equation
Therefore, the area of regular polygon with 5 sides is 689.65m²
