Answer:
The measurement of the width is <u>20 ft</u>.
Step-by-step explanation:
Given:
The perimeter is 94 ft and the length is 27 ft.
Now, to find the unknown measurement.
Perimeter = 94 ft.
Length = 27 ft.
Let the width of the rectangle be 
So, to get the width we put formula of perimeter:


<em>Subtracting both sides by 54 we get:</em>
<em />
<em />
<em>Dividing both sides by 2 we get:</em>

Therefore, the measurement of the width is 20 ft.
B. adding 40 to both sides of the equation
x^2 - 40 = 0
x^2 = 40
x = ± √40
