Answer:
88 ft
Step-by-step explanation:
11ft times 8ft equals 88 ft. Its the same so the area is 88 ft.
Area of a rectangle is length x width.
Let the width = x
The length would be x +7. ( 7 inches longer than the width)
Area = 20
Set up the formula:
20 = x * x+7
Simplify the right side:
20 = x^2 + 7x
Subtract 29 from both sides:
X^2 + 7x -20 = 0
Solve using the quadratic equation
X = -b + sqrt(b^2 -4ac) / 2a
X = -7 + sqrt(7^2-4(1)(-20) / 2(1) (exact answer)
X = 2.178908 ( as a decimal)
The width is 2.178907 inches (round as needed)
The length would be 9.178907 inches ( round as needed.)
Depending on how you round, when you multiply them together you get approximately 20 square inches.
Answer:
The value of 2008 is 112% of the Value of 2007.
But we need 100% of the year of 2007.
So 350000/112=3125=>1%
3125*100=312500=>100%
The answer is $312500
