# Medians in RT

The rectangular triangle ABC has a length of 10 cm and 24 cm. Points P, Q, R are the centers of the sides of this triangle. The perimeter of the PQR triangle is:

Result

o =  30 cm

#### Solution:

$a=10 \ \text{cm} \ \\ b=24 \ \text{cm} \ \\ \ \\ c=\sqrt{ a^2+b^2 }=\sqrt{ 10^2+24^2 }=26 \ \text{cm} \ \\ o=\dfrac{ a+b+c }{ 2 }=\dfrac{ 10+24+26 }{ 2 }=30 \ \text{cm}$
