A. Length - 100 ft Width - 50 ft is the measurement of Tony's backyard.

Albert's Perimeter = 2 (l+w) = 2 (40+20) = 2 (60) = 120 ft.

Tony's Perimeter = 120 ft * 2.5 = 300 ft

Tony's length = 40 ft * 2.5 = 100 ft

Tony's widht = 20 ft * 2.5 = 50 ft

To check tony's perimeter:

P = 2 (l + w) = 2 (100 + 50) = 2 (150) = 300 ft.
