1. Answer:

   28 feet long

   Step-by-step explanation:

   we find the area of the first lawn using recent angle formula (l)(w)=a

   (7)(3)

   21

   Now we multiply this by 4 since the second lawn is four times it

   21×4

   84

   Now we rearrange the rectangle area formula to where length is what we are trying to find

   a=(l)(w)

   /w. /w

   a/w=l

   Now we fill in this formula

   84/3=a

   28

   Hopes this helps
