  1. Which of the following is measured in square units (like square inches or square centimeters)?

    1. Time
    2. Perimeter (measured in inches, feet, or meters)
    3. Length (measured in inches, feet, or meters)
    4. Area (space inside a shape)

  2. Look at the rectangle below. How many square units cover the entire shape?

    1. 7 square units
    2. 8 square units
    3. 14 square units
    4. 12 square units

  3. Ava has two square tiles. One tile has an area of 9 square inches. The other has an area of 16 square inches. Which tile is smaller?

    1. The 9 square inch tile
    2. The 16 square inch tile
    3. Both tiles are the same size
    4. Cannot be determined

  4. What is the difference between area and perimeter?

    1. Area only works for squares
    2. Area measures the distance around; perimeter measures space inside
    3. Area measures space inside; perimeter measures distance around
    4. They measure the same thing

  5. Maria draws a rectangle on a grid. The rectangle is 5 units long and 3 units wide. She counts 12 unit squares instead of 15. What did Maria do wrong?

    1. She counted the perimeter instead of area
    2. She counted only the edges, not the whole inside
    3. She multiplied 4 and 3 instead of 5 and 3
    4. She added instead of multiplied

  6. Look at these two rectangles. Rectangle A is 6 units by 2 units. Rectangle B is 3 units by 4 units. Which has the greater area?

    Recognize and Measure Area visual for G3-C06-T01-Q006
    1. Rectangle A
    2. Rectangle B
    3. Cannot determine
    4. They are equal

  7. Look at this shape made of square units on a grid. Count the squares to find the area without multiplying. Which square unit measurement is correct?

    Recognize and Measure Area visual for G3-C06-T01-Q007
    1. 6 square units
    2. 7 square units
    3. 8 square units
    4. 9 square units

  8. Look at the grid. What is the area of the shaded shape?

    Recognize and Measure Area visual for G3-C06-T01-Q009
    1. 8 square units
    2. 10 square units
    3. 12 square units
    4. 15 square units

Answer key and explanations

  1. D. Area (space inside a shape)

    Area is the amount of space inside a flat shape. It is measured in square units such as square inches, square feet, or square centimeters. Perimeter and length use regular units (inches, feet), not square units.

  2. D. 12 square units

    Count the rows: 3 rows. Count the columns: 4 columns. Multiply: \(3 \times 4 = 12\) square units.

  3. A. The 9 square inch tile

    The tile with an area of 9 square inches is smaller than the tile with 16 square inches. Smaller area means less space inside.

  4. C. Area measures space inside; perimeter measures distance around

    Area is the space inside a shape (measured in square units). Perimeter is the distance around a shape (measured in regular units).

  5. B. She counted only the edges, not the whole inside

    Area is the space INSIDE a shape. Maria must count or multiply to find all the unit squares, not just the border. \(5 \times 3 = 15\) square units.

  6. D. They are equal

    Rectangle A: \(2 \times 6 = 12\) square units. Rectangle B: \(3 \times 4 = 12\) square units. Both have the same area.

  7. D. 9 square units

    Count the rows: 3 rows. Count the columns: 3 columns. The area is 9 square units.

  8. C. 12 square units

    The rectangle is 4 units wide and 3 units tall. \(4 \times 3 = 12\) square units.
