Question

the perimeter of an isosceles triangle is 20 by 24 cm if the unequal side is 5 by 68 CM then find the length of the equal sides of the isosceles triangle​

Answer 1

Given Perimeter = 20/24 cm

Length of unequal side = 5/68 cm

Let the length of equal side be x cm

Length of other equal side will also be x cm.

As we know, Perimeter of Triangle = Sum of Its sides.

=> x + x + 5/68 = 20/24

2x + 5/68 = 20/24

2x = 20/24 - 5/68

2x = 155/204

2x ÷ 2 = 155/204 ÷ 2

x = 155/408

Therefore, Length of other two sides is 155/408 cm.
