The base of an isosceles triangle is4/5 cm. The perimeter of the triangle is 4*2/15 cm.
What is ​

Answer 1

Step-by-step explanation:

Base = 4/5

perimeter = 42/15

let the length and breadth is ( x )

perimeter of the isosceles triangle is

= base + length + breath = 42/15

= 4/5 + x + x = 42/15

= 4/5 + 2x = 42/15

= 2x = 42/15 - 4/5

= 2x = 42 - 12

= 2x = 30

= x = 15
