A school has an auditorium with 35 rows, with 42 seats in each row. How many people can sit in this auditorium?

Correct Answer

Given: 35 rows, 42 seats per row

Formula: Total seats = Number of rows × Seats per row

Substitution: Total seats = 35×4235 \times 42

Calculation: 35×4235 \times 42 = 35 × (40 + 2) = 35×4035 \times 40 + 35×235 \times 2 = 1,400 + 70 = 1,470

Answer: 1,470 people can sit in the auditorium.

Explanation

This is a multiplication word problem. The total number of seats equals the number of rows multiplied by the number of seats per row: 35×4235 \times 42 = 1,470.

Solution Steps

  1. Step 1: Identify the operation: 35 rows × 42 seats per row

  2. Step 2: Calculate: 35×4235 \times 42 = 35 × (40 + 2) = 35×4035 \times 40 + 35×235 \times 2

  3. Step 3: 35×4035 \times 40 = 1400, 35×235 \times 2 = 70

  4. Step 4: 1400 + 70 = 1470
