Answer:
Step-by-step explanation:
our triangle has one length: 3.76+1.7=5.46
another side: 1.36+1.1=2.46
last side: 7.1+5.1=12.20
Perimeter is=5.46+2.46+12.20=20.12 cm

Answer:
Step-by-step explanation:
Let a be the length of the altitude, then from the given triangles, applying the basic proportionality theorem, we get

⇒
⇒
⇒
⇒
Thus, the length of altitude is: 12 cm.
Now, 
⇒
⇒
Also, 
⇒
⇒
Thus, the lengths of the legs of this triangle are 14.83 and 20 cm.
