Answer:
a=√89 b=√45
Step-by-step explanation:
in ∆1
p= 8cm
b= 5cm
h=a
according to Pythagoras theorem
(h)^2=(p)^2+(b)^2
(a)^2=64+25
a=√89
in ∆2
p=b
b=12
h=17
similarly as questions 1
(h)^2=(p)^2+(b)^2
17^2={b}^2+12^2
189-144=(b)^2
b=√45

Answer:
A = 9.4 as you do 8^2 + 5^2 which is 89 and the squared root is 9.4 hence 9.4 is the answer to A, the way how to work this out is you square,square,add then square root it. ( B = 12.0)
