L = 2W + 1..................(1)
2L + 2W = 74
2L = -2W + 74..............(2) Adding (1) and (2):-
3L = 75
L = 75/3 = 25
W = (25 - 1) / 2 = 12
length is 25 inches and width = 12 inches
Answer:
Last option: 
Step-by-step explanation:
If the shell of a bass drum was cut down one side and laid flat, the resulting shape would be a rectangle.
The area of a rectangle can be calculated with the formula:

Where l is the lenght and w is the width.
In this case, the lenght of the rectangle obtained (the lenght of the shell) is the circumference of the drum.
Remember that the circumference of the circle can be calculated with:

Where r is the radius of the circle.
Then:

The width is the height of the shell:

Then, substituting into
, you get:

Since the triangles are similar, they will have proportional sides. With this knowledge, we can make the proportion
to solve for x.
Firstly, cross multiply: 
Next, divide by 10 on both sides, and your answer will be 4 = x, or the first option.
