Question

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

Answer 1

Assalmualikum below is ur solution

Solution :

Length of equal sides = 23 /4 cm .

Let the third side be X cm.

Perimeter of isosceles triangle = 18 .

2 × (equal sides) + Third size = 18 .

2× (23/4 ) + X = 18 .

23/2 + X = 18 .

23 + 2 X = 36 .

2 X = 36 - 23 .

X = 13 / 2cm .

Third side = X = 13 / 2 cm.
