Answer:

Step-by-step explanation:

Remark

The Perimeter of a rectangle is found using

P = 2L + 2w

Givens

L = s+2t

w = s + 5t

Solution

P = 2(s + 2t) + 2(s + t5)                     Remove the brackets

P = 2s + 4t + 2s + 10t                       Combine

P = 4s + 14t

Answer P = 4s + 14t                         This cannot be reduced any further.
