Answer 1

14t + 4s

Explanation:

(s + 5t) + (s + 2t) + (s + 5t) + (s + 2t)

s + s + s + s + 5t + 5t + 2t +2t

4s + 14t

Answer 2

Answer: Option A: 14t + 4s

Explanation:

To find the perimeter of a shape, add up all of its side lengths. We know that the length of the rectangle is (s + 2t), and its width measures (s + 5t).

To find the perimeter, multiply the width by 2 and the length by 2 and add those expressions:

P (perimeter) = 2(s + 2t) + 2(s+5t)

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

P = 4s + 14t or 14t + 4s

Hope this helps.
