pls follow and select my answer as brainlist answer
Step-by-step explanation:
in triangle ABC
AB = 4x +1cm , BC = 2x -1cm ,AC = xcm
perimeter of triangle= sumof all 3 sides
280= AB+BC+AC
= 4x +1+2x -1+x {+1 ,-1 get cancelled}
280 = 7x
X=280/7
X=40 ,
AC=40, AB=4×40+1= 161, BC=2×40-1=79
verify
AC+AB+BC=280
40+161+79=280
