Question 251322
c=7
16-7=9=a+b
b=9-a
a+(9-a)+7=16
a^2+b^2=c^2
a^2+(9-a)^2=c^2
a^2+81-18a+a^2=49
2a^2-18a+32=0
a^2-9a+16=0
a^2-9a     =-16
a^2-9a+(81/4)=(81/4)-16 completing the square.
(x-(9/2))^2=17/4
x-(9/2)=+-sqrt(17)/2
x=(9+sqrt17)/2, x=(9-sqrt(17))/2
((9+sqrt17)/2) * ((9-sqrt(17))/2) * (1/2)
=8m^2
