Respuesta :

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
