Answer

length = width + 15

Area = length * width; area is 54 square feet.

Two equations are:

L = W + 15

L * W = 54

To solve, we substitute first equation into second equation:

(W + 15) * W = 54

w^2 + 15w = 54

w^2 + 15w - 54 = 0

(w+18)(w-3) = 0

w = -18 or 3

The width cannot be negative, so 3 is the width and since length is 15 more than width, length is 18:

Length = 18 feet

Width = 3 feet

The expected value of the game is $8.75.

----------------------

The expected value is the sum of each outcome multiplied by it's probability.
A probability is the number of desired outcomes divided by the number of total outcomes.

The probability of spinning a 2 and a vowel is: $\frac{1}{4} \times \frac{2}{8} = \frac{2}{32}$ .
Thus, $\frac{2}{32}$ probability of getting $50.

The probability of spinning 2 and a consonant is: $\frac{1}{4} \times \frac{6}{8} = \frac{6}{32}$

Thus, $\frac{6}{32}$ probability of getting $25.

The probability of spinning 1 and a vowel is: $\frac{3}{4} \times \frac{2}{8} = \frac{6}{32}$ .
Thus, $\frac{6}{32}$ probability of getting $5.
