Beside their adventure camp, Emek and Luna found two rectangular spaces for a garden. They marked each space with square units. The first space had 4 rows of 8 squares, for an area of 32 square units. The second had 5 rows of 7 squares, for an area of 35 square units. Their plants needed at least 34 square units. After comparing the areas, Emek and Luna chose the second space and happily began planting.

Challenge 1 of 4
Hint
Compare the first space's area of 32 square units with the 34 square units the plants need.
Emek says the first garden space is large enough because its area is 32 square units. The plants need at least 34 square units. Which statement correctly checks Emek's idea?
Emek is correct because 32 is greater than 34.Emek is not correct because 32 is less than 34.Emek is correct because the first space has 4 rows.Emek is not correct because 32 is greater than 35.Correct! The first space is too small because 32 is less than 34.
Try again. Check whether 32 square units is at least 34 square units.

Hint
Find the difference between 35 square units and 34 square units.
The second garden space has an area of 35 square units, and the plants need at least 34 square units. How many square units larger is the second space than the minimum area the plants need?
Correct! The second space is 1 square unit larger than the minimum area needed.
Try again. Subtract the minimum area needed from the area of the second space.

Hint
Think of the rows as equal groups of squares.
Luna wants to check the area of the second garden space without counting every square one at a time. It has 5 rows of 7 squares. Which calculation correctly verifies its area?
5 + 7 = 127 - 5 = 25 x 7 = 355 + 5 + 5 + 5 + 5 = 25Correct! Five rows with 7 squares in each row make 35 square units.
Try again. Use the number of rows and the number of squares in each row to check the area.
