Hello!
Let's write this as a system of equations.
L=3w
wL=432
Let's plug in our value for L into the second equation, and solve for w.
w(3w)=432
3w²=432
w²=144
w=12
Now, let's plug our w value into the first equation.
L=3(12)
L=36
Therefore, the length is 36 and the width is 12.
I hope this helps!

Step-by-step explanation:
Answer:
Slope of JK = -4/5
Step-by-step explanation:
We know that GHJK is a parallelogram. If GHJK is a parallelogram then the sides of parallelogram will be:
GH, HJ, JK, GK
Hence the opposite sides will be:
GH and JK
HJ and GK
We know that opposite sides of parallelogram are parallel to each other and the slopes of parallel lines is equal.
So the slope of GH and JK will be equal.
And slopes of HJ and GK will be equal.
As we are given the slope of GH which is -4/5, the slope of JK will also be -4/5 because both lines are parallel.
