Ответ:
Option D: w + 3w + w + 3w = 56
Step-by-step explanation:
Given the perimeter of a rectangle of 56 yards, for which its length is triple the width.
Let P = perimeter of a rectangle = 56 yards
L = length of a rectangle = 3W
W = width of a rectangle
The formula for finding the perimeter of a rectangle is:
P = 2L + 2W or P = 2(L + W)
Substitute the value of the length into the perimeter formula:
P = 2L + 2W
P = 2(3W) + 2W = 3W + 3W + W + W = 56 yards
Therefore, the correct answer is Option D: w + 3w + w + 3w = 56
