Set the width to be x. Thus, the length is 4x.
The perimeter is 2(x+4x)=100, so x=10.
Plugging in x=10, you get that 4x=40.
So, the area of the rectangle is 400 
.
Because there are 100 centimeters in a meter and you are asking for area, you must multiply by 
to get 4000000 
.
Answer:
Lowest score needed=4.92
Step-by-step explanation:
Using the standard normal distribution table we find the value of standard normal deviate corresponding to area of 15%
For area of 15% we have Z= -1.04
Thus we have
Applying values we get
Thus lowest score needed = 4.92
Answer:
The diameter is any straight line that passes through the center of the circle, which endpoints can lie on. The radius is half the diameter. They help us find the circumference of a circle
There are 12 inches in a foot. To find how many inches are in 5 feet, multiply by 12:
5*12 = 60 inches
Add the 8 additional inches:
60 + 8 = 68 inches
The answer is 68.
