The tile along the edge of a triangular community pool needs to be replaced. which expression represents the total perimeter of the pool edge? 12x2 + 15 20x2 + 25 12x2 + 8x + 25 24x2 + 16x + 50

Solution:

As, given tile along the edge of a triangular community pool needs to be replaced.

There may be single tile, two tiles ,or more than two tiles along the edges of triangle.

Keeping in mind, if tiles are in the shape of rectangle , or Square

→→The total perimeter of pool edge which is in the shape of a triangle= 3 × (Either length or breadth of rectangle or side of square which is in the shape of tile )

→Means, out of the options given, the option which is completely divisible by 3 will be perimeter of pool edge.

Option (1) : 12 x² + 15= 3 ×(4 x² + 5)→→is the only option which is completely divisible by 3.So, this can be perimeter of the pool edge.
