Length- 40 feet
Width- 20 feet
The perimeter of Tony's rectangular backyard is 2.5 times the perimeter of Albert's backyard. Which of the following best represents Tony' backyard?
A. length-100 feet Width- 50 feet
B. length- 16 width-20
C. length- 100 width-20
D. length-50 width- 25

Answer 1

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.
