Answer: A=100ft^2

Step-by-step explanation:

You can use the following formula calculate the area of a rectangle:

A=w*h

Where "w" is the width of the rectangle and "h" is the height of the rectangle.

In this case you know that this rectangle is 12.5 feet wide and  8 feet tall.  Therefore, you can substitute values into the formula to find its  area.

Then, you get that the area of this rectangle is the following:

A=(12.5ft)(8ft)\\\\A=100ft^2

The length of a rectangle is 5 inches less than twice its width. The perimeter of the rectangle is 26 inches. What is the width
Yakvenalex [24]

Answer:

w= 6

Step-by-step explanation:

I just started by making an educated guess using the values already given. Then I inserted that into the problem to see if it worked.

L= 2w - 5

I used 6 as a random, educated guess for the value of w.

L = 2(6) - 5

L = 12-5

L = 7

Then, multiply L by 2 to account for both side lengths of the rectangle.

7(2)= 14

Subtract that value from the total perimeter to find what the width must equal.

26 - 14 = 12

Divide that answer by 2 since there are two sides for width.

12/2 = 6

I know this was kind of long, but I hope it helps! :)

lubasha [3.4K]
Total Time = (M x K) / (M + K)
5 = (8 x K) / (8 + K)
40 + 5 K = 8K
40 = 3K
King can do the job in 13.33 Hours

King could mow (1 / 13.33) of the lawn in one hour.

The is the mean score ? A.25.5 B.26 C.
pentagon [3]
So to find the mean you add up all the numbers (or the exam scores) which will get you 212 then you take the number and divide it by the total numbers in the set (how many numbers did you add up?)

212 divided by 8 is 26.5 which would be C. I hope this helps!
