Question

the perimeter of triangle is 140 metre if the length of its two of its sides measure 35 m and 60 m find the length of third side​

Answer 1

Step-by-step explanation:

let the third side be x

perimeter of triangle= 140m

its first side= 35m

its second side= 60m

perimeter of triangle= sum of all its sides

140= 35+60+x

x= 140-35-60

x= 55m
