Final answer:
Ricky will need 36 inches of wire to make a diamond with sides that are 9 inches long because a diamond shape has four sides of equal length.
Step-by-step explanation:
To calculate the amount of wire Ricky needs to make a diamond with sides that are 9 inches long, we need to consider the properties of a diamond shape. A diamond shape, in geometric terms, is a rhombus, meaning all its sides are of equal length. Since there are four sides to a rhombus and each side of Ricky’s diamond is 9 inches, we simply multiply the length of one side by the number of sides.
Wire needed = Length of one side × Number of sides
Wire needed = 9 inches × 4
Wire needed = 36 inches
Therefore, Ricky will need 36 inches of wire to create a diamond with 9-inch sides.
