Question

Jessica has 12 square tiles that she

wants to use to make rectangles. Find 3
different rectangles she can make using
all 12 square tiles in each of the
rectangles. Include the area and
perimeter of each rectangle. Then
compare the areas and perimeters.​

Answer 1

List the factors of 12

1,12

2,6

3,4

That is the side lengths of the 3 rectangles

All the areas will be 12 because they are the factors 12

factors multiply to be a number

(length + width) x 2 = perimeter

1+12=13x2=26

1 by 12 has a perimeter of 26 and area of 12

2 by 6 has a perimeter of 16 and area of 12

3 by 4 has a perimeter of 14 and area of 12

Hope this helps. If you have any questions you can ask
