Question

The perimeter of an isoscles triangle is 18 cm . If one of the equal side is 23/4 cm long . find the measure of the third side​

Answer 1

Answer:

Third side = 13/2 cm

Step-by-step explanation:

Let the third side be x cm

Perimeter of a triangle = sum of all sides

We are given one of the two equal sides as 23/4...

So, 23/4+23/4+x=18

x= 18-(23/4+23/4)

x= 13/2

Answer 2

Answer:

given that

perimeter of an isosceles triangle = 18cm

one side = 23/4 cm

second side = 23/4 cm ( in isosceles triangle two sides are equal)

third side = x cm

We know that

Perimeter of triangle = sum of all sides

18 =. 23/4 + 23/4 + x

18. =. 64/4 + x

18. =. 11.5 + x

18 - 11.5 = x

x = 6.5

Therefore , third side is 6.5 cm.
