Answer 1

HELLO
============================

ANSWER -----

In an Isosceles Triangle, Two of the three sides are equal to each other.

Let both the equal sides measure x and x

Perimeter = Sum of all sides
Perimeter of a triangle = sum of all three sides

Perimeter (given) = 4 whole 2/15
=> 62/15

Equation will be :

4/3 + x + x = 62/15
4/3 + 2x = 62/15

2x = 62/15 - 4/3

2x = 42/15

x = 42/15 × 1/2

x = 21/15

=> Length of either of two remaining sides equals 21/15 cm
