Answer:
Let x be the width of the screen and
x + 30 be the length of the screen
Area of the screen = 10384 square feet
=>x(x+30) = 10384
x^2 + 30x = 10384
x^2 + 30x - 10384 = 0
Splitting-
x2+118x - 88x -10384 = 0
x(x+118) -88(x+118) = 0
(x+118)(x-88) = 0
x=-118,88
Since width should be positive,
width = 88 feet
length = 118 feet
