Question

The non-equal side of an isosceles triangle is 6 cm. If the perimeter of the triangle is
24 cm, then find its all sides.​

Answer 1

Answer:

Thus all sides are 6cm,6 cm and 12 cm

Step-by-step explanation:

let un equal side=x then

perimeter

=x+6+6=24

x=24-12=12 cm

Thus all sides are 6cm,6 cm and 12 cm

Answer 2

Answer:

9

Step-by-step explanation:

let the equal side be named as a and the base be b

the perimeter = 24 cm

perimeter = 2s + b

24 = 2a + b

24 = 2a + 6

24 - 6 = 2a

18 = 2a

18/2 = a

9 = a

check

perimeter = 2s +b

p = 2 ×9+6

p = 18 +6

p = 24 cm
