Question

A plot consists of a rectangular garden measuring 8 m by 10 m, surrounded by a

path of constant width, as shown in the diagram.
The total area of the plot (garden and path) is 143 m2.
Find the width of the path. Use x to represent the width of the path.

Answer 1

x= 3m
The length of the new sides are 11 and 13. I got this by looking at the factors of 143 and looking for numbers that fit the 8:10 ratio.
