Answer:

P = 127

Explanation:

Since a rectangle has two pairs of congruent sides, we can set one pair equal to each other to find x.

4x + 16 = 2(3x-1)

4x + 16 = 6x - 2

18 = 2x

x = 9

Plug in the value of x into one of the original equations to find the length and width.

4(9) + 16 = 52

1/2 (9) + 7 = 11.5

Perimeter = 52 + 52 + 11.5 + 11.5 = 127
