Question 150832
L/w=3/2


Cross multiply
3w=2L
Divide by 3
w=2L/3


L+20/w-5=2/1
Cross multiply
2w-10=L+20


Plug in w
2(2L/3)-10=L+20


Distribute
4L/3-10=L+20


Subtract 4/3L from both sides
-10=-1/3L+20


Subtract 20 from both sides
-30=-1/3L


Multiply both sides by -3
90=L


90/w=3/2
Cross multiply
180=3w
60=w


Answer:
Length=90
Width=60
