At their forest campsite, Emek and Luna needed a dry floor inside their rectangular tent. They had square mats, each covering 1 square unit. Emek placed 6 mats in each row, and Luna made 4 equal rows with no gaps or overlaps. They counted 24 square mats altogether, so the tent floor covered 24 square units. They checked every corner to make sure the rectangle was completely covered. Just before nightfall, their warm, dry tent was ready.

Hint
Think about 4 equal rows with 6 square mats in each row.
Emek placed 6 square mats in each row, and Luna made 4 rows. Which calculation finds the area of the tent floor?
6 + 4 = 106 + 6 = 126 x 4 = 2424 + 4 = 28Correct! Four rows of 6 square mats cover 24 square units.
Try again. Find the total number of square mats in 4 rows of 6.
Next🎉 Congrats! You got this question!
Hint
The tent floor already has 24 mats. Add 6 more mats.
Suppose Emek and Luna add one more row of 6 square mats to the tent floor. How many square mats would there be altogether?
Correct! Adding 6 mats to 24 gives 30 mats.
Try again. Start with the 24 mats and add one row of 6.

Hint
Think about how much area one mat covers and how many mats cover the floor.
Each square mat covers 1 square unit. Why does using 24 mats with no gaps or overlaps mean the tent floor has an area of 24 square units?
Each mat covers 1 square unit, so 24 mats cover 24 square unitsEach row always covers 24 square unitsEvery rectangle has an area of 24 square unitsThe 4 rows make the area 4 square unitsCorrect! Twenty-four mats that each cover 1 square unit cover 24 square units altogether.
Try again. Each mat covers exactly 1 square unit of the floor.
