Soln:- length =30 m
diagonal=34 m
√l^2+b^2 =34
(√30^2 +b^2)^2 =34^2 [squaring both sides]
30^2+b^2=1156
900+b^2=1156
b^2=1156-900
b^2=256
b=√256
=16 m
Perimeter =2(l+b)
=2(30+16)
=92m
diagonal=34 m
√l^2+b^2 =34
(√30^2 +b^2)^2 =34^2 [squaring both sides]
30^2+b^2=1156
900+b^2=1156
b^2=1156-900
b^2=256
b=√256
=16 m
Perimeter =2(l+b)
=2(30+16)
=92m
