Gabrielle wants to put up around her garden. It cost $1.50 per yard for 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 l Langton of 4 yards and a width of 3 yards
To find the cost of the garden, we need to substitute the values of l and w into the formula $1.50(2l + 2w).
For a garden that has a length (l) of 4 yards and a width (w) of 3 yards, we can substitute these values into the formula:
Cost = $1.50(2*4 + 2*3)
= $1.50(8 + 6)
= $1.50(14)
= $21
Therefore, the cost for a garden that has a length of 4 yards and a width of 3 yards is $21.
