Arectangular doormat is 21 inches long and has an area of 714 square inches. find its width. is the doormat wide enough to cover an entryway of 36 inches wide?

34; 34 inches is not long enough

Step-by-step explanation:

A doormat is the shape of a rectangle and its area uses A=l*w. If the area is 714 and its length is 21, then 714 = 21*w. Solve for w.

714=21w

714/21= 21w/21

34 = w

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

i think 5 miles per hour
