    Full step-by-step solution

    Step 1: The area of a rectangle is found by multiplying its length by its width. Step 2: The playground's length is 24 meters and its width is 18 meters. Step 3: Multiply 24 × 18. Step 4: First, multiply 24 × 10 = 240. Step 5: Then, multiply 24 × 8 = 192. Step 6: Add the two results: 240 + 192 = 432. Step 7: The total area is 432 square meters.

  2. A farmer is harvesting apples from her orchard. She has 24 apple trees, and each tree produces about 75 apples. How many apples will the farmer harvest in total? Answer: 1800 Solution: The farmer has 24 trees Each tree produces 75 apples To find the total apples, multiply the number of trees by apples per tree: 24 × 75 Break it down: 24 × 70 = 1680 Then 24 × 5 = 120 Add them together: 1680 + 120 = 1800 The farmer will harvest 1800 apples in total.

  3. A farmer plants an apple orchard in a rectangular field. The field has 8 rows of apple trees, and each row contains 12 trees. If you visualize this arrangement as a rectangular array, how many apple trees are in the orchard? Answer: 96 Solution: We are told the farmer plants an apple orchard in a rectangular field. There are 8 rows of apple trees, and each row contains 12 trees.
    Full step-by-step solution

    We are told the farmer plants an apple orchard in a rectangular field. There are 8 rows of apple trees, and each row contains 12 trees. Step 1: Understand the arrangement. A rectangular array means we can multiply the number of rows by the number of trees in each row to find the total number of trees. Step 2: Write the multiplication. Number of rows = 8 Number of trees per row = 12 Total trees = 8 × 12 Step 3: Perform the multiplication. 8 × 12 = 96 Step 4: Interpret the result. Since 8 rows each with 12 trees gives 96 trees, the total number of apple trees in the orchard is 96. Final answer: 96

  4. Emma is helping her teacher set up chairs for the school concert. She needs to arrange chairs in 6 rows, with 24 chairs in each row. How many chairs does Emma need to set up in total?
