The area of any regular polygon is equal to one half the product of the apothem and the perimeter of the polygon. A regular polygon is any polygon that has equal length of its sides. A pentagon has 5 sides so if it is a regular pentagon then the perimeter is 5 times the length of one side. The apothem of a polygon is the length of a line from the center of the polygon to the middle of one of its side. We calculate the area as follows:
Area = apothem (perimeter) / 2
Area = 7 ft (5 (10 ft)) / 2
Area = 175 ft^2
Answer:
40 percent
Step-by-step explanation:
Start by taking the difference of the two values:
35-25 = 10.
the $10 is how much the value increased by.
To get the percent that the $25 increased by, take 10/25 to get .4
This .4 can then be turned into a percentage when you multiply it by 100. = 40 percent.
You can check your answer by finding 40 percent of 25, which is 10.
Answer:
if a triangle had two right angles it would not be complete as to make it a triangle all corners have to meet while a 2 right angled triangle does not meet that.
i believe this is the answer
Width of the rectangle is 10.67 ft
<u>Step-by-step explanation:</u>
Step 1:
Let the width of the rectangle be x. Then length = 2x + 12
Given width + length = 44ft ⇒ x + 2x + 12 = 44
⇒ 44 = 3x + 12
⇒ 32 = 3x
⇒ x = 32/3 = 10.67
Width of the rectangle = 10.67 ft
