Final answer:
The fencing of a square garden with an area of 144 square feet will require a total of 48 feet of fence. If the cost is $3.50 per linear foot, the whole fence will cost $168.
Explanation:
The problem is asking how much it will cost to fence a square garden with an area of 144 square feet if the fence's cost is $3.50 per linear foot.
Since the garden is square, each of its four sides has the same length. The area of a square can be found by squaring one of its sides. Therefore, to find the length of one side, you'll need to take the square root of the area. The square root of 144 is 12, so each side of this garden is 12 feet in length.
Given a square, we have four equal sides. Hence the total fence needed would be 4 times the length of one side, so we'll need 4*12 = 48 feet of fence.
The cost of the fence is $3.50 per linear foot. So for 48 feet fence, it would cost 3.50 * 48 = $168.
