W= width
l= 2w= length
Perimeter of a Rectangle Formula
P= 2(l + w)
substitute 2w for l in equation
180= 2(2w + w)
multiply 2 by parentheses
180= 4w + 2w
combine like terms
180= 6w
divide both sides by 6
30 yards= w
LENGTH
2w= 2(30)= 60 yards
CHECK:
180= 30 + 60 + 30 + 60
180= 90 + 90
180= 180
ANSWER: the width is 30 yards and the length is 60 yards

Answer:
1. Re-writing an equation to remove all the variables.
Step-by-step explanation:
Backtracking is the procedure required for solving problems that has series of parts combined as one. It involves the retracing each part after one or two parts has been solved to solve the whole problem.
In mathematics when given an equation with variables, the solution can be obtained by calculating the values of each variable. To determine the final solution sometimes requires substitution procedure.
The best option that describe backtracking in maths-sense is; re-writing an equation to remove all the variables.
Stimulus.
A stimulus is a reaction to environmental changes.
