Length=96 feet
Width=70 feet
Step-by-step explanation:
Let the length = l
The width 26 feet less than its length=l-26
Perimeter of the giant rectangular movie screen= 332 feet
Perimeter of a rectangle = 2(L+W)
332=2(l+l-26)
332=2(2l-26)
Expanding the brackets
332=4l-52
4l=332+52
4l=384
l=384/4=96
The Length of the giant rectangular movie screen is 96 feet.
The Width, W=l-26=96-26=70 feet
