Answer:
The answer to your question is length = 19 and width = 12 ft
Step-by-step explanation:
Data
Perimeter = 62 ft
Width = length - 7
Process
1.- Write equations that help to solve this problem
Perimeter = P = 2w + 2l
w = l - 7
2.- Substitution
62 = 2w + 2l Equation l
w = l - 7 Equation ll
Solve the system of equations by substitution
- Substitute equation ll in equation l
62 = 2(l - 7) + 2l
-Simplification
62 = 2l - 14 + 2l
62 + 14 = 4l
76 = 4l
l = 76/4
l = 19 ft
-Find w
w = 19 - 7
w = 12 ft
