Question 5 (i)

A path 1 m wide is built along the border and inside a square garden of side 30 m. Find:
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
$=(AB\times AD)-(EF\times EH)$
$=(30\times 30)-(28\times 28)$
$=900-784$
$=116m^2$
