Answer:
Step-by-step explanation:
1. 
19² = 17² +x² 
19² - 17² = x² 
√361-289 =x
√72 = 8.5 ≈ x
Area = base*h/2 = 17*8.5/2 ≈ 72.3
Perimeter = 19+17+8.5= 44.5
and so on...
2.
x²= 5² +13²...
A= 5*13/2 =...
P= 5+13+x=...
3. 
20² = 10² +x²...
A=10*x/2=...
P=20+10+x=...
4.
x² = 5² +14²...
A=5*14/2 =...
P= 5+14+x = ...
