Question

An isosceles triangle has perimeter 30 cm and each of the equal sides is 12 CM then, what is its third side​

Answer 1

6 is third side

Step-by-step explanation:

perimeter=30cm and

equal side of an isosceles is 12cm

isosceles means two sides so 12+12=24

so now third side =30-24=6 is the third side

Answer 2

Answer:

iski third side hogi 6 cm.

Step-by-step explanation:

perimeter of triangle = 30cm

one side = 12 cm

perimeter of triangle = sum of all sides

perimeter = 12+12+y (let third side be y)/ x bhile sakte hain

=> 30 = 12+12+y

30 = 24+ y

30-24 = y

6 = y

so third side of the trianlge is 6cm.
