All of these rectangles have the same area. Use the associative property and move the parenthesis to find the unknown side lengths.

8 x 6 = 8 x (2 x 3) = (8 x 2) x 3 Area = 48 sq. cm.

8 x 6 = 8 x (2 x 3) = 8 x (2 x 3) Area = 48 sq. cm.

All of these rectangles have the same area. Use the associative property and move the parenthesis to find the unknown side lengths.

8 x 6 = (4 x 2) x 6 = 4 x (2 x 6) Area = 48 sq. cm.

8 x 6 = (4 x 2) x 6 = (4 x 2) x 6 Area = 48 sq. cm.

Label the side lengths of each part of the rectangle. Then, find the total area of the large rectangle by adding the areas of the two smaller rectangles together.

( 5 + 4 ) x 7 (5 x 7 ) + (4 x 7 ) 35 + 28 area = 63

( 4 + 4 ) x 7 (4 x 7 ) + (4 x 7 ) 28 + 28 area = 56

( 5 + 5 ) x 7 (5 x 7 ) + (5 x 7 ) 35 + 35 area = 70

( 7 + 7 ) x 7 (7 x 7 ) + (7 x 7 ) 49 + 49 area = 98

Label the side lengths of each part of the rectangle. Then, find the total area of the large rectangle by adding the areas of the two smaller rectangles together.

3 x (10 + 3) (3 x 10) + (3 x 3) 30 + 9 area = 39

13 x (10 + 3) (13 x 10) + (13 x 3) 130 + 39 area = 169

10 x (10 + 3) (10 x 10) + (10 x 3) 100 + 30 area = 130

3 x (10 + 3) (3 x 10) + (3 x 10) 30 + 30 area = 60
