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.

Answer 1

To find the cost of the border for Gabrielle's garden, we are given the formula 1.50(2l+2w), where l is the length and w is the width of the garden.

Substituting the given values l=4 and w=3 into the formula, we have 1.50(2(4)+2(3)).

Simplifying, we get 1.50(8+6) = 1.50(14) = $<<1.5*14=21>>21.

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