Using Pythagoras theorem we find length=12cm
Perimeter =2(l+b)
=2(17)
=34cm
Perimeter =2(l+b)
=2(17)
=34cm

Width=5cm
Diagnol=13cm
Length=25+x=169 (pythagoras theoram)
= x=169-25
x=144
Hence length =12 because 144 is square of 12.
Perimeter=2(l+b)
=2(12+5)
=2*17
=34cm
Diagnol=13cm
Length=25+x=169 (pythagoras theoram)
= x=169-25
x=144
Hence length =12 because 144 is square of 12.
Perimeter=2(l+b)

this answer is wrong the correct answer is 34
