Answer:

PS = 37

Step-by-step explanation:

The opposite sides of a rectangle are congruent, thus

perimeter = 2(3x + 1) + 2(4x - 3) = 136 ← distribute and simplify left side

6x + 2 + 8x - 6 = 136

14x - 4 = 136 ( add 4 to both sides )

14x = 140 ( divide both sides by 14 )

x = 10

Hence

PS = 4x - 3 = (4 × 10) - 3 = 40 - 3 = 37
