Cognitive demand: medium. Typical question shape: Composite figure; sum areas of parts.
Sofia is planting a garden in her backyard. She wants to create a rectangular garden that is 8 feet long and 5 feet wide. What is the area of her garden in square feet?
- 40 ✓
- 30
- 50
- 45
Why: To find the area of a rectangle, you multiply the length by the width. So, the area of Sofia's garden is 8 feet × 5 feet = 40 square feet.
Nia is planting a garden in her backyard. She has a rectangular area that is 12 feet long and 9 feet wide. If she wants to cover the entire area with soil, how many square feet of soil does she need?
- 108 ✓
- 72
- 21
- 27
Why: To find the area of Nia's rectangular garden, multiply the length by the width: 12 feet * 9 feet = 108 square feet. Therefore, Nia needs 108 square feet of soil to cover the entire area.
Imani has a rectangular garden that is 8 feet long and 5 feet wide. She wants to put a fence around the entire garden. How many feet of fencing does she need to buy?
- 26 ✓
- 40
- 30
- 50
Why: To find the amount of fencing Imani needs, calculate the perimeter of the rectangular garden. The formula for the perimeter P of a rectangle is P = 2 * (length + width). Here, the length is 8 feet and the width is 5 feet. So, P = 2 * (8 + 5) = 2 * 13 = 26 feet. Therefore, Imani needs to buy 26 feet of fencing.
Sofia wants to plant a garden in her backyard. The length of the garden is 8 feet and the width is 5 feet. What does the area of the garden represent in this context?
- The amount of space available for planting flowers ✓
- The length of the garden only
- The number of plants that can be grown
- The distance from her house to the garden
Why: The area of the garden, calculated as length times width (8 feet × 5 feet = 40 square feet), represents the total space available for planting flowers. This means option A is correct because it directly relates to what the area indicates in terms of gardening.
Sofia wants to plant a garden in her backyard. She has a rectangular space that is 12 feet long and 8 feet wide. If she plans to plant flowers in half of that space, what is the area in square feet that she will use for the flowers?
- 48 ✓
- 96
- 24
- 72
Why: To find the area of the rectangular space, you multiply the length by the width: 12 feet * 8 feet = 96 square feet. Since Sofia is using half of that space for flowers, you divide that area by 2: 96 square feet / 2 = 48 square feet. Therefore, the area she will use for flowers is 48 square feet.
Tatiana wants to plant a vegetable garden in her backyard. She has a rectangular area that is 12 feet long and 8 feet wide. What is the best way to describe the area of her garden in square feet?
- 96 ✓
- 20
- 32
- 24
Why: To find the area of a rectangle, you multiply the length by the width. Here, the length is 12 feet and the width is 8 feet, so the area is 12 * 8 = 96 square feet. This represents the total space available for Tatiana's vegetable garden.
Carlos has a rectangular garden that is 12 feet long and 8 feet wide. He wants to find out what the area of his garden is to plan for planting flowers. Which expression represents the area of Carlos's garden?
- 12 × 8 ✓
- 12 + 8
- 12 - 8
- 12 / 8
Why: To find the area of a rectangle, you multiply the length by the width. In Carlos's case, the area is represented by the expression 12 × 8, which equals 96 square feet. This shows that option 12 × 8 is the correct expression to find the area of his garden.
