Gabriella wants to put a border around her garden. It cost one One dollar, 50 cents Per yard for the materials. Use 1.50. (2l+2w) where l is the length and w is the width of her garden to find the cost for a garden that has a length of 4 yards and a width of 3 yards

To find the cost for a garden that has a length of 4 yards and a width of 3 yards, we need to substitute the given values into the expression 2l + 2w.

For the length l = 4 yards and the width w = 3 yards,
2(4) + 2(3)
= 8 + 6
= 14

Therefore, the cost for a garden that has a length of 4 yards and a width of 3 yards is 14 * 1.50 = $<<14*1.50=21>>21. Answer: \boxed{21}.

To find the cost for a garden with a length of 4 yards and a width of 3 yards, you can use the formula: (2l + 2w).

Substituting the values, we have:
(2 * 4) + (2 * 3)

Simplifying the equation, we get:
8 + 6

Therefore, the total cost for a garden with a length of 4 yards and a width of 3 yards would be:
14 yards.

However, there is an additional cost mentioned, which is $1.50 per yard for the materials. So, to find the total cost, we need to multiply the yardage by the cost per yard:

14 * $1.50

Multiplying, we get:
$21

Therefore, the cost for a garden with a length of 4 yards and a width of 3 yards, including the border materials, would be $21.

To find the cost for a garden with a length of 4 yards and a width of 3 yards, we can use the formula:

Cost = (2 * length + 2 * width) * cost per yard

Given:
Length (l) = 4 yards
Width (w) = 3 yards
Cost per yard = $1.50

Substituting the values into the formula, we have:

Cost = (2 * 4 + 2 * 3) * $1.50
Cost = (8 + 6) * $1.50
Cost = 14 * $1.50
Cost = $21

Therefore, the cost for Gabriella's garden is $21.
