Key Concepts

• Multiplying fractions
• Area = Length x Width

Solving the Question

We're given:

• 
  `A=(36x^2)/(y)\hspace{4}cm^2`
• 
  `l = (9x)/(y^2)`

`A=l*w`

⇒ Isolate w:

`w=A/ l`

⇒ Plug in given:

`w=(36x^2)/(y)/ (9x)/(y^2)`

⇒ Multiply by reciprocal:

`w=(36x^2)/(y)* (y^2)/(9x)`

⇒ Reduce fractions:

`w=(36x)/(y)* (y^2)/(9)\\\\w=(36x)/(1)* (y)/(9)\\\\w=(36xy)/(9)`

Answer

`w=(36xy)/(9)`
