Calculate Total Houses: Finding Product of 4 Streets × 20 Average Houses

To solve this problem, we’ll follow these steps:

• Step 1: Determine the number of streets.
• Step 2: Determine the average number of houses per street.
• Step 3: Calculate the total number of houses by multiplying these two values.

Now, let's work through each step:

• Step 1: The number of streets is given as 4.
• Step 2: The average number of houses per street is 20.
• Step 3: Using the formula $\text{Total number of houses} = \text{Average number of houses} \times \text{Number of streets}$, we have:

$\text{Total number of houses} = 20 \times 4 = 80$

Therefore, the solution to the problem is $80$.
