Given that Jordan has a new puppy and she wants to put a fence around part of her yard to cover an area of 200 square feet.
Now we have to find what dimensions (length x width) should she make the rectangular area. None of the length or width are given so there can be lots of answers.
Since area is rectangular and we know that rectangle has different value of length and width so we just need to find two factors of given area 200 square feet.
For example 20 times 10 is 200.
So the dimension of the rectangular area will be:
Length = 20 feet and width = 10 feet
Now perimeter of the rectangle is given by formula:
Perimeter = 2(length+width) = 2(20+10)=2(30)=60
Hence perimeter is 60 feet.
A-action games
s-sports games
a+s=47
a=s+21
I replace the action games in the first equation
s+21+s=47
2s+21=47
2s=47 - 21
2s=26
s=26:2
s=13 number of sport games
a=13+21
a=34 number of action games
I think the correct answer from the choices listed above is option D. The equation that would satisfy all of the points plotted above would be y=-2x. From the plot, we can see that the y-intercept is equal to zero and by using two points we can calculate the slope to be equal to -2. Giving an equation which is y=-2x.
Answer: perimeter = 26.5
Area = 106
Step-by-step explanation:
The given polygon is an octagon. The apotherm which is the perpendicular line from the midpoint of the octagon is 8,
The formula for determining the area of a polygon is expressed as
Area = a² × n × tan 180/n
Where n represents the number of sides of the polygon.
n = 8
Therefore,
Area = 8² × 4 × tan(180/8)
Area = 256 × tan 22.5
Area = 106
The formula for determining the perimeter of a regular polygon is
P = 2 × area/apotherm
Perimeter = 2 × 106/8
Perimeter = 26.5
