Answer:

Perimeter of triangle PQR = 181.5 mm

Explanation:

Midsegment theorem states that,

"Midsegment connecting the midpoints of the two sides of a triangle is parallel and half of the length of the third side"

From the figure attached,

PQ =
(1)/(2)(EF)

=
(83)/(2)

= 41.5 mm

PR =
(1)/(2)(GF)

=
(110)/(2)

= 55 mm

QR =
(1)/(2)(GE)

=
(170)/(2)

= 85 mm

Perimeter of triangle PQR = PQ + QR + PR

= 41.5 + 55 + 85

= 181.5 mm
