Step-by-step explanation:

the perimeter of a rectangle is

2×length + 2×width

now we also know that

length = 1/3 × width + 5

so, when we bring this into the main equation for the perimeter :

2× (1/3 × width + 5) + 2×width

2/3 × width + 10 + 2×width

2/3 × width + 10 + 6/3 × width

8/3 × width + 10
