Answer:
28k
Step-by-step explanation:
The perimeter is the sum of the four equal-length sides:
P = 7k +7k +7k +7k
P = k(7 +7 +7 +7)
P = 28k . . . . perimeter of the rhombus
__
Of course, multiplication was invented to make repeated addition easier. Here, the perimeter is 4(7k) = 28k, no like terms to combine.
50 miles = 1 hour
50 x 1 = 50
a. 50 miles x 2 hours = 100 miles
b. 50 miles x 4.3 hours = 215 miles
c. Converting minutes to hours, it would make 20 minutes become 0.333 hours.
50 x 0.333 = 16.65 miles
