Answer: 
Step-by-step explanation:
The perimeter of a rectangle can be calcualated with this formula:
Where "l" is the lenght and "h" is the height.
The area of a rectangle can be found with this formula:
Where "l" is the lenght and "h" is the height.
In this case we know that:
Therfore, we can susbsitute them into and solve for "h" in order to find its value:
Find two number whose sum is 3 and whose product is -40. These are -5 and 8. Then, factorizing, we get:
The positive value is the height. Then:
Since the length is 3 centimeters greater than its height, we get that this is: Then:
Substituting values into , we get that the perimeter is:
Answer:
13/20p
Step-by-step explanation:
Here, we want to write an expression from the given statement
We start from the product of 20 and p
Mathematically. that is 20 * p = 20p
Now to find the ratio, we simply place 12 over the product
We have this as;
13/20p
190+135+220=445. 360(the degrees in a circle)/445(the number of students)=0.81. Each student is worth 0.81 degrees. 0.81x190(the number of students that like the program)=135.9. That rounds up or 136 so the answer is 136 degrees.

Step-by-step explanation:
Diameter of the target is 2196 mm
Step-by-step explanation:
We are given Circumference of target = 6,895.4400000000 mm.
We need to find the diameter of target.
The formula used is:
Putting values:
We know that 
So, Finding Diameter:
So, Diameter of the target is 2196 mm
