12 . a) a'2 + b2 = c'2
20'2 + 32'2 = c2
400 + 1024 = 1424 cm'2
[ 1424=1424'2 ]

b) a'2 + b'2 = C2 .
576'2 + 100'2 = C'2
331776+10000=341776 cm '2

c)
a'2 + b'2 = c'2
25'2 + 90'2 = c'2
625+8100=8725cm'2
[8725=8725cm'2 ]

d ) a'2 + b'2 = c'2
12'2 + 12'2 = c'2
144+144=288cm '2
[ 288=288 cm'2 ]


17 .
a) a'2 + b'2 = c'2
21'2 + 28'2 = ;
441 + 784 = c2
[ 1225= c'2 ]

b) a'2+b'2=c'2
12'2 + 5'2=c'2
144 + 25 = c'2
169=c'2
