Thank you for the opportunity to help you with your question!

parameter of triangle is = 76.25

parameter formula = a+b+c

let first half is = x

then second half according to the given condition = x+x = 2x

third side = x+7.25

so put the values in parameter formula

parameter = a+b+c

76.25 = x+2x+x+7.25

76.25-7.25 = 3x

69= 3x

x= 23

so the values of all sides is

 first side is = 23

then second side according to the given condition = x+x = 46

third side = 30.25
