The length is 22.5 and the width is 19.5
Step-by-step explanation:
2L + 2W = P
\/
2L + 2W = 84
\/
W + 3 + W + 3 + W + W= 84
\/
4W + 6 = 84
\/
4W = 78
\/
W = 19.5 L = 19.5 + 3 = 22.5
I hope this helps, have a nice day! :D

Step-by-step explanation:
Answer: Melanie swam 63 minutes more in second week.
Step-by-step explanation:
Given , Time taken by Melanie in first week to swim = 142 minutes
Combined time taken by her in first two weeks in swimming = 347 minutes
Now , time taken by her in second week = (Combined time of first two week) - (Time taken in first week)
= 347-142 minutes
= 205 minutes
Clearly , 205 > 142 i.e. She swam more in second week than first week./
Difference i= 205-142 = 63
Therefore, Melanie swam 63 minutes more in second week.
50 miles, t=0 is the start
45 miles each 1 hour
A. d= 45•t+50
