Answer: 40
Step-by-step explanation:
Finding perimiter is simple! You add the L & the W by each other and then times that by 2!
15 + 5 = 20
20 X 2 = 40!

Answer:
use foil method-first inside outside last
Step-by-step explanation:
Hello!
According to the dashes, you can see that the two separate triangles are congruent. Therefore, these two angles are congruent. We will solve below.
6n-10=50
We add 10 to both sides.
6n=60
Divide both sides by 6.
n=10
Therefore, our answer is A) 10.
I hope this helps!
Given that the central angle of a polygon is 18, then the number of sides of the polygon will be:
360/18
=20 sides
thus the side length will be:
144/20
=7.2 ft
hence the area will b given by:
p=s×n
a=s/[2tan(180)/n]
where:
Area=(a×p)/2
p=perimeter, s=side length, n=number of sides
p=7.2×20=144
a=7.2/[2tan (180/20)]=22.73
thus
A=(144×22.73)/2
A=1632.524 ft²
