Question

Each of the two equal sides of an isosceles triangle is three times as large as the third side if the perimeter of the triangle is ₹28 cm, find each side of the triangle ​

Answer 1

Answer:

12cm, 12cm, 4cm

Step-by-step explanation:

let isosceles sides =x

other side=x/3

perimeter of triangle=x+x+x/3

28=2x+x/3

by LCM

28=7x/3

84=7x

x=12

other side will be x/3or 12/3

=4

Answer 2

Answer:

ANSWER :

Sides are:-

4 cm, 12 cm, 12 cm

EXPLANATION :

Let the third side be x

Then the two equal sides = 3x

Perimeter = x + 3x +3x

28 = 7x

x = 28/7

x = 4 cm

Third side = 4 cm

Two equal sides are 3x = 12 cm
