Width = 7cm
Length = 13cm
<u>Explanation:</u>
Area of rectangle =
Let width of the rectangle = b ,
So, length = b+6
Area of rectangle = (length X width) - eqn 1
Putting the value of length and width in above equation 1,
On solving the quadratic equation we get,
b = 7cm
So, width (b) = 7cm
and length = 7+6
l = 13cm
Hence,
Width = 7cm
Length = 13cm
We will use the binomial coefficient formula to work out the answer
The formula is given by:
Where:
'n' is the total population or sample population
'r' is the number of pick
We have:
n = 20
r = 3
Substitute these values into the formula we have
Answer:
There are 1140 different ways of picking three winners out of 20 people
