Milo wants to put a fence around the dog park near his house. He measures the sides and finds they are 7\text{ m}7 m7, start text, space, m, end text and 8\text{ m}8 m8, start text, space, m, end text long. He multiplies 7\times27×27, times, 2 and 8\times28×28, times, 2 and finds he needs 30\text{ m}30 m30, start text, space, m, end text of fencing.

The measurement represent the perimeter of the dog park

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

table 3 represents a direct variation function. : )
