Answer:

  length, width, perimeter

Step-by-step explanation:

_____

If we assume that the length and width of the patio are desired, then those are the selections for the first two boxes.

The planes are about 78.5 km apart.

viktelen [127]
300=x+1.9x
I got this by dividing the problem into two parts x[the speed of the first half] plus 1.9x [the speed of the second half increased by 1.9] both of those together should give you 300. 
I went further and solved this...If you placed 103.5 into this problem for x you should get 300.15!
