variable width, set it to 0
variable length, set it to 0
variable area
variable ratio
variable gravitational_pull

enter while loop (condition is width and length being in range 1-400 inclusive)
    display "Please only enter WIDTH and LENGTH between 1 - 400"
    display "Please enter the WIDTH of your kite in centimeters"
    input value into width

    display "Please enter the LENGTH of your kite in centimeters"
    input value into length

display "Width" + width + "Length" + length

set area equal to (width * length) / 2
set area equal to itself / 10000 (this converts to square meters)

display "Area in suqare meters" + area

variable mass, set it equal to (135 * area) / 1000 (finds mass in kg/meter^2)

set gravitational_pull equal to mass * 9.8

set ratio to width / length

if ratio is equal to or more than 1
    display "Warning: a lower aspect ratio would provide more stability"
    display "Current aspect ratio: " + ratio + " (width/length)"
