Perimeter of rectangle = 2 ( length + breadth )
Here, given rectangle has dimension
Length = and breadth =
Thus, perimeter of rectangle =
Thus, perimeter of rectangle is ........(1)
Perimeter of rectangle , when x = 3,
Put x= 3 in (1) ,
Thus, represents the total perimeter of the table, and if x = 3 the lentgh of entire rubber bumper is 12 feet.
