Confused on question in screenshot.

Answer 1

70,5.

Explanation:

Let's find QS.

∠QHS = 90º, so:

`QS^2 = a^2+((b)/(2))^2\\ QS^2 = (2√(11))^2+((34)/(2))^2\\ QS^2 = 4*11 + 17^2\\ QS^2 = 44+289 = 333 \\ QS = √(333) = √(3*3*37) = 3√(37)`

QS = QR =
`3√(37)`

`P = QR+QS+RS\\ P = 3√(37) + 3√(37) + 34\\ P = 6√(37) + 34`

`√(37) = 6,08276...`

`P = 6*6,08276+34 = 36,48+34 = 70,4965...`
`= 70,5`
