5/12 is less than 1/2 because 6/12 = 1/2
Therefore, there are not enough 1/12 pieces to equal or exceed 1/2.
We know that
[Area of the regular pentagon]=5*[side length * apothem] / 2
side length=7.1 m
apothem=4.9 m
then
Area=5*[7.1 * 4.9] / 2-----------> 86.975 m²----------> 87 m²
the answer is 87 m²
Answer:
Brainliest!
Step-by-step explanation:
Since the interior angle is 144 degree, each exterior angle is 180 - 144 = 36 degrees
number of sides = 360/36 = 10
The polygon is decagon with 10 sides
