Explanation
1-0.18=0.82.
0.82 • 12 = 9.84
A square has 4 sides of equal length
so the perimiter is 4s where s is the length of 1 side
so if the length of 1 side is 14 then
P=4s
P=4(14ft)
P=56ft
the perimiter is 56ft
10 yards per 5min is
10yrd/5min
first convert it into yards per minute
10yrds/5min = 2yrds/1min
let's first so the yards to feet part first
1 yrd = 3 feet
2yrds/min * 3ft/1yrd
so now we have
6yrds/min
now convert minute to hour
1 hour = 60 mins
6yrds/min * 60min/1hr
=360/1hr
remember so that units cancel
