2( l+b ) = 34
l= 17 - b
using pythogoram theorm
ab square + bc square = ac square
b square +( 17- b ) square = 13 square
2bsquare -34b + 120 = 0
2( b square - 12 b -5b +60) = 0
factors b-5 , b-12
l = 17- b
l = 17 -5 = 12
l= 17 - b
using pythogoram theorm
ab square + bc square = ac square
b square +( 17- b ) square = 13 square
2bsquare -34b + 120 = 0
2( b square - 12 b -5b +60) = 0
factors b-5 , b-12
l = 17- b
l = 17 -5 = 12
