Since there are all parallel, we can create a proportion to find the answer.
Let x be the length of plot 3 across Cheshire Road.
[tex] \frac{x}{40} = \frac{56}{48} [/tex]
Multiply both sides by 40 to get our answer.
[tex]x= 40* \frac{56}{48} [/tex]
Simplify the right side of the equation.
[tex]x= 46 \frac{2}{3} [/tex]
Hope this helps and have an awesome day! :)
