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
2c is a factor of both terms.
.. area = 2c(c+1)
Possible expressions for length and width are
1, 2, c, 2c, c+1, 2(c+1), c(c+1), 2c(c+1).
