Let the points be A,B,C

A(0,0)
B(24,16)
C(8,20)

$\\ \bull\sf\leadsto AB=\sqrt{(24-0)^2+(16-0)^2}=\sqrt{24^2-16^2}=\sqrt{576-256}=\sqrt{320}=17.4units$ (leg3)

$\\ \bull\sf\leadsto AC=\sqrt{(8-0)^2+(20-0)^2}=\sqrt{8^2+20^2}=\sqrt{64+400}=\sqrt{464}=21.4units$ (leg1)

$\\ \bull\sf\leadsto BC=\sqrt{(24-8)^2+(26-20)^2}=\sqrt{16^2+(-4)^2}=\sqrt{256+16}=\sqrt{272}=16.4units$ (leg2)

We have to find perimeter

$\\ \bull\sf\leadsto Perimeter=AB+AC+BC$

$\\ \bull\sf\leadsto Periemter=17.4+16.4+21.4$

$\\ \bull\sf\leadsto Perimeter=55.2units$

The length of leg3=17.4units
