Example Question #71 : How To Find The Perimeter Of A Square
Know that in a Major League Baseball infield the distance between home plate and first base is 90 feet and the infield is a perfect square.
If a batter ran to first, then started to run toward second base, but decided to go back to first base when they were halfway to second, how far would they have run in total by the time the made it back to first base?
If they run this way they run 90 feet between home plate and first base, 45 feet between first base and the point where they turn around, and 45 more feet from where they turned around to first base. So, they ran
Example Question #71 : How To Find The Perimeter Of A Square
Know that in a Major League Baseball infield the distance between home plate and first base is 90 feet and the infield is a perfect square.
If a baserunner is on third base and the batter hits a home run, how far to the two players run in total?
The baserunner on third base runs 90 feet to home plate and is done running.
The batter who hit the home run runs all four sides of the square, so they run 360 feet.
Example Question #261 : Squares
Know that in a Major League Baseball infield the distance between home plate and first base is 90 feet and the infield is a perfect square.
If a confused batter hits a home run and then runs the bases backwards, how far will they in total run if they make it all the way back to home plate before they realize their mistake, and then run all of the bases again in the correct order?
If running all of the bases once is 360 feet,
then running the bases twice is
Example Question #911 : Plane Geometry
A square has an area of 
If the area is 20.25 square inches, that means that the side lengths are all the square root of 20.25.
To find the perimeter, multiply by 4:
Example Question #72 : How To Find The Perimeter Of A Square
True or false: The perimeter of a square with sidelength ten inches is three feet.
True
False
False
The perimeter of a square is four times the length of a side; since the given square has ten inches as the common length of its sides, its perimeter is four times this, or
Since one foot is equal to 12 inches, three feet are equal to
The perimeter of the square is therefore not equal to three feet.
Example Question #74 : How To Find The Perimeter Of A Square
The area of the square 
The formula for the area of a square with given side length 
The formula for the perimeter of a square with given side length 
Hence, the perimeter of the square 
Example Question #71 : How To Find The Perimeter Of A Square
If the area of a square is 144, what is the perimeter?
First we need to find the measure of one side. Since formula for area of a square is
we can plug in area and find side
we have to take the square root of each side to solve for S
so
Now that we have our side we can solve for perimeter. The formula for perimeter of a square is
Since we know S=12 we multiply 12 x 4 and we get 48.
Example Question #75 : How To Find The Perimeter Of A Square
A square has an area of 
The area of a square is:
So using the numbers:
Therefore, every side of the square is 25.
Now to find the perimeter, a square has 4 equal sides:
The perimeter of the square is 100
