Step-by-step explanation:
p=2L+2w
factorise
p=2(L+w)
p=2(20+14)
p=2(34)
p=68
This is also a perimeter of a rectangle
300 words per page
68 second per page
then 300 words per 68 seconds
1. if 68 seconds = 300 words
then 60 seconds = 60*300 / 68 = 264.71 words
answer: Reading rate = 264.71 ≈ 265 words per minute
2. if 68 seconds = 1 page
then 3600 seconds = 3600/68 = 52.94 ≈ 53 pages per hour
(note! 60seconds*60minutes =3600 seconds= 1 hour)
answer: Reading rate = 52.94 ≈ 53 pages per hour
