Gabrielle wants to put a border around her garden. It costs $1.50 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 substitute l = 4 and w = 3 into the formula 1.50(2l+2w):

Cost = 1.50(2 * 4 + 2 * 3)
= 1.50(8 + 6)
= 1.50(14)
= $21.00

Therefore, the cost for a garden that has a length of 4 yards and a width of 3 yards is $21.00.

To find the cost for a garden with a length of 4 yards and a width of 3 yards, you can use the formula: 1.50(2l + 2w).

First, we substitute the given values into the formula:
l = 4 yards
w = 3 yards

1.50(2(4) + 2(3))

Next, we simplify the expression inside the parentheses:
1.50(8 + 6)

Then, we simplify the expression:
1.50(14) = $21

Therefore, the cost for a garden with a length of 4 yards and a width of 3 yards is $21.

To find the cost of putting a border around Gabrielle's garden, we will use the formula given: 1.50(2l+2w), where l is the length and w is the width of the garden.

Given that the length of Gabrielle's garden is 4 yards and the width is 3 yards, we can substitute these values into the formula and calculate the cost.

So, the cost of putting a border around the garden would be:

Cost = 1.50(2 * 4 + 2 * 3)
= 1.50(8 + 6)
= 1.50 * 14
= $21.00

Therefore, the cost for Gabrielle to put a border around her garden would be $21.00.
