Answer:
4990
Step-by-step explanation:
Multiply 638 by 5 then add 1800 and that's your answer
Lets say that the length of a rectangle is 12 cm and the width is 5 cm, you would add 12+12+5+5 (as in the length on both length sides and the width on both sides) so the perimeter of this rectangle is: 34 cm
An example of a unit rate would be driving a car at 50 miles per hour. 50 miles per every 1 hour is a unit rate.
140cm. I hope this is correct. Please mark brainilest if it is! Have a great day!
You can search it up on the internet and it would be 4.3
