Answer: $12a
Step-by-step explanation:
Cost of brick = $2 per foot
Cost of edging needed=?
Shape of garden = hexagonal= 6 sides and all sides are equal
The perimeter of a regular hexagon = 6×a
Where a = length of one of the sides , since the sides are equal.
Cost of edging = perimeter size (in feet) * cost per foot
Cost of edging = 6a * $2
Therefore, cost of edging = $12a
Where a = length of it's side in feet.
