  10 +4√14

Step-by-step explanation:

PQR is a right triangle. Leg QR is shown as 5 units. Leg RP will be the sum of the radius of the circle (5) and the external measure, 4:

  RP = RT +TP = 5 + 4 = 9

Then by the Pythagorean theorem, the side PQ can be found to be ...

  PR^2 = PQ^2 +QR^2

  9^2 = PQ^2 +5^2

  PQ = √(81 -25) = √56 = 2√14

So, the sum of lengths PQ and QR is ...

  PQ +QR = 2√14 +5

The perimeter of this symmetrical figure is twice this value, so is ...

  perimeter = 2(2√14 +5)

  perimeter = 10 +4√14

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
