    Answer:

    Step-by-step explanation:

    Perimeter = L1 + W1 + L2 + W2          L1 = L2 = L  = 70 ft       W1 = W2 = W = 30 ft

                     = L + W + L + W        

                     = 2L + 2W          

                     = 2(70) + 2(30)

                     = 140  +  60

                     = 200

    Perimeter the movie screen  is 200 ft
