Step-by-step explanation:
Area = Length x Width
A. With these dimensions, the area would be 18 sq units
1 * 18 = 18
B. With these dimensions, the area would be 18 sq units
3 * 6 = 18
C. With these dimensions, the area would be 18 sq units
6 * 3 = 18

Answer:
12
Step-by-step explanation:
We already found x in a previous problem.
x = 6
The right triangle on the right side with sides x and y is also a 30-60-90 triangle.
The hypotenuse is twice the short leg.
x = 6
y = 2x
y = 12
Standard form : Ax + By = C
12y = 9x - 30
-9x + 12y = -30 ....some teachers accept this, with A being negative
but if not, then it is this :
9x - 12y = 30
