Answer 2

Explanation

Given that the area of the side block is represented by

`w\mleft(3w\mright)=67,500`

The value of w can be found below;

`\begin{gathered} w(3w)=67,500 \\ 3w^2=67500 \\ \text{Divide both side by 3} \\ w^2=(67500)/(3) \\ w^2=22500 \\ w=\sqrt[]{22500} \\ w=150 \end{gathered}`

Answer: 150
