Answer:
width =20
length = 1
Step-by-step explanation:
length = w - 19
A = l*w
20 = (w-19) * w
20 = w^2 - 19w
Subtract 20 from each side
0 = w^2 - 19w - 20
Factor
0 = (w+1)(w-20)
Using the zero product property
w+1 = 0 w-20 = 0
w = -1 w=20
Widths cannot be negative
w=20
l = 20-19 = 1
About 2% chance.
There are ten numbers and you want to choose a number less than three. There are only two numbers less than three; 1 & 2. Because there are only 2 numbers less than three and 10 to choose from, it becomes a 2% chance.
