Find the area of the regular decagon if the apothem is 2.8ft and a side is 1.8ft

geniusboy [140]

DECA=10, decagon = 10 sides.

since each side is 1.8 long, all 10 sides will be 10*1.8 or 18 units long, so that'd be the perimeter then,

$\bf \textit{area of a regular polygon}\\\\
A=\cfrac{1}{2}ap~~
\begin{cases}
a=apothem\\
p=perimeter\\
------\\
a=2.8\\
p=18
\end{cases}\implies A=\cfrac{1}{2}(2.8)(18)$

Answer: True, False, False, False, False

Step-by-step explanation:

a) 5x - 7(x - 1)

5x - 7x + 7

-2x + 7 ⇒ a = -2, b = 7 One Solution

b) 3(x - 5) - 7

3x - 15 - 7

3x - 22 ⇒ a = 3, b = -22 One Solution

c) 2 - 7x + 3 + 4x

4x - 7x + 3 + 2

-3x + 5 ⇒ a = -3, b = 5 One Solution

d) -3(x - 3) - 1

-3x + 9 - 1

-3x + 8 ⇒ a = -3, b = 8 One Solution

e) -5x + 2 + 2x + 4

-5x + 2x + 2 + 4

-3x + 6 ⇒ a = -3, b = 6 One Solution
