Answer: 230cm²
Step-by-step explanation:
>We can do this by splitting the figure into 2 trapeziums.
>Additionally, you can see that both trapeziums bear the same lengths a and b. Hence, we can use this formula:
.
>Thus,
Area = 
Add 5 to both sides of the equation.
x=-14+5
Add -14 and 5.
x=-9
Answer: Third option
Step-by-step explanation:
You have the function:

Then, if the value of x increases by 1, you obtain:
-Rewrite the function:
-Substitute values for x into the function and observe what happen to y. Then:
x=1
x=2
x=3
The value of y is doubled.
To find the width, divide the area by the length.
Width = 375 / 25
Width = 15 feet.
