5 feet is 60 inches. The other side with the two lines is also 17.2 in. The two sides with only one line will each be (60 - 17.2 - 17.2) / 2, because they're equal. That will make both sides with the one mark 25.6 / 2, or 12.8 in.
You can't find the area unless you have the angle of the vertices or the height.
235.24 + 45.58 = 280.82
280.82/2 = 140.41
each check was for $140.41
Area = length x width. So, you can't find the actual length and width from the area because there are infinite possibilities.
But you can figure out a set of likely solutions. For example:
If A = 35 l = 1, 5, 7, 35 and w = 1, 5, 7, 35.
We now know that the length and width must be one of these 3.
Even if the area is a prime number, there are still infinite fractional possibilities.
So, there really is no way to actually find the length and width from the area.
1) Let's solve for x, writing this equation.
3x +8*59 =0
3x +472=0 <em>Subtract 472 from both sides</em>
3x = -472
x= -472/3 or -157.33
2) So the answer is x= -472/3
The answer is d) that is the answer.
