Question

Plz help meh out on my math hw

Answer 1

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!
