Question

A path 1 m wide is build around a garden that is a 30-meter square. What is the area taken by the path?

Answer 1

Length of outer boundary =30m

So area of outer boundary =30×30

= 900m²

Length of inner boundary of path=30-1= 29m

Inner area =29×29 =841m²

So area of path is= outer area - inner area

=900- 841

= 59m²
