Answer:
5 ft
Step-by-step explanation:
Area of a rectangle
length x width
(3x-2) * (x) = 65
3x^2 - 2x - 65 = 0
Δ/4 = 1 + 195 = 196
x1 = (1 + 14)/3 = 5
x2 (1-14)/3 = -13/3 (not acceptable because a length can’t be negative)

Answer:
Let's see...
Step-by-step explanation:
*Note: we can't find the exact area of the shaded figure right off the bat, we have to find the area of a bigger figure and divide it by 2.
<h3>The coordinates of the bigger figure:</h3>
A = (0,0)
B' = (0,4)
C = (5,4)
D' = (5,0)
Note: the little [ ' ] next to the B and D indicate that it is not the same coordinate as B and D, just that those points would be the same as point B and D.
<h3>That being said, what is the area of the bigger figure?</h3>
A = l * w
A = 4 * 5
A = 20 units²
<h3>Now, divide the Area by 2:</h3>
A = 20 ÷ 2
<em>A = 10 units²</em>
I hope this helps!
