Question

A path 1 m wide is built along the border and inside a square garden of side 30 m Find :
i) The area of the path

Answer 1

Side of the square garden $=30$ m

and width of the path along the border $=1$ m

Side of square garden without path $=30–(1+1)=30–2=28$ m

Now Area of path $=$ Area of $ABCD–$ Area of $EFGH$

$=(AB\times AD)-(EF\times EH)$

$=(30\times 30)-(28\times 28)$

$=900–784=116m^2$
