Answer:
perimeter of triangle= sum of all sides
given, base= 2/7cm and perimeter= 30/7
in an isosceles triangle two sides are same so,
let the two equal sides be x now,
= x+x+2/7 cm= 30/7 cm
= 2x+2/7= 30/7 cm
= 2x= 30/7-2/7
= 2x= 28/7
= x= 28/7*1/2
= x= 14/7 cm
= x= 2cm
therefore, measure of 2 equal sides of isoscele triangle will be 2cm
