Question

perimeter of an isocles triangle is 50 cm if one of the two equal sides are 18 cm find the third side

Answer 1

Hey...!!!

Perimeter = 50 cm
Sides = 18 cm and, 18 cm

So,
Sum of sides = perimeter
18 + 18 + X = 50
36 + x = 50
X = 50 - 36
X = 14
So, length of third side = 14 cm

Hope it helps..!!!!
