The area of one square is 49 square inches.
What is a square?
A square is a two-dimensional figure and a four-sided polygon which has it's all sides equal in length and the measure of the angles are 90 degrees. The total interior angle is 360 degrees.
For the given situation,
The figure is made up of two identical squares. So it forms a rectangle.
Let width be x then length be 2x.
Perimeter of rectangle = 42 inches
The formula of perimeter of rectangle is

first solve for the perimeter of the rectangle
2w + 2l = 42
since the length of the rectangle is twice as long as the length and width of the square
2w = l
solve using substitution
2w + 2(2w) = 42
2w + 4w = 42
6w = 42
w = 7
are is length x width. a square has the same length and width
7 x 7 = 49
the area of one square is 49

23.50 * 3 = 70.50
23.25(3) + 17 = 86.75
Now, they are not equal.
Try another one!
27.50 * 5 = 137.50
23.25*5 + 17 = 133.25
Not correct either!!
Try another!
27.50 * 6 = 165
23.25 *6 + 17 = 156.50
NO! Lets try the second one!!
27.50*4 = 110
23.25 * 4 + 17 = 110
THIS ONE IS CORRECT!
Answer: 4 hours is when they have the same charges.
$27.50×4= $110.
$23.25+17+4= $110
Thats the answer. Try the other answer and none will be the same.

Answer:
When adding fractions you want the denominators of your fractions to be alike.
The first thing you can do is add your two whole number 4 and 6. 4+6=10.
Now you want to combine your fractions, 3/8 and 3/4. Both fractions need to have like denominators. In order to do this we would change the 3/4 so it has a denominator of 8. I choose 8 because you can take 2*4 to get 8. Since we multiplied the denominator by 2, we have to do the same with the numerator, 3*2=6.
Your fraction is now 6/8.
We can down add 3/8 + 6/8= 9/8
Since 9/8 is improper we need to change it into a mixed number. In order to do this we need to take 9/8 which is 1 and 1/8
We now have 1 1/8 and don't forget the 10 from up above.
10+1 1/8= 11 1/8
Your final answer would be 11 1/8
Hope this helps ;)

It will take the first horse 2.5 hours to run a mil
It will take the second horse 4 hours to run a mil
Find the required graph attached.
The formula for calculating speed is expressed as:
- Speed = Distance/Time
- Time = Distance * Speed
Get the speed of each horse
Speed for the first horse = 5/2 = 2.5 miles/hr
Time = 2.5 * 1
Time = 2.5 hours
Hence it will take the first horse 2.5 hours to run a mile
Speed for the second horse = 4/1 = 4 miles/hr
Time = 4 * 1
Time = 4 hours
Hence it will take the second horse 4 hours to run a mile
