Perimeter is the continuous line that forms the boundary of a closed geometric figure.
Perimeter of a pentagon = 5a ; where a is the length of its side.
a = 3√5 ⇒ P = 5 * 3√5 = 15√5
Perimeter of an octagon = 8a ; where a is the length of its side.
a = 3√5 ⇒ P = 8 * 3√5 = 24√5
Answer: x=7
Step-by-step explanation:
-4x+26=-2
-26
-4x=-28
Divide by -4
=7
15 cards = 9$
1 card = (9/15)$
12 cards = 9/15 * 12
= 108/15
= 7.2$
Answer:
Not enough information, need a picture.
Step-by-step explanation:
Circumference of a circle with radius 8 =
c = 2 pi 8
For semi circle we will divide this by 2 and then add the base segment which is the length of the radius * 2.
p = (2 * 3.14 * 8)/2 + 16
perimeter = 41.12 m
