Question

each of equal sides of isosceles triangle is 4 times the third side.the perimeter of the triangle is 117 cm .find the side of the triangle

Answer 1

Let third side be x,

Each equal side = 4x 

=================

Perimeter = sum of all sides

117 = x + 4x + 4x

117 = 9x 

117/9 = x 

13 = x 

======================


unequal side =x= 13 cm 

Each equal side = 4x =4(13) = 52 cm


i hope this will help you

Answer 2

Heya !!!



Let ∆ABC is an isosceles triangle.


In which,


AB = AC


And,


Let BC is X cm.



According to the,


Each equal sides = 4( Different side)


AB = AC = 4BC


AB = AC = 4X cm.



Perimeter of isosceles triangle = 117 cm


AB + AC + BC = 117



4X + 4X + X = 117



9X = 117


X = 117/9


X = 13 cm.


BC = X = 13 cm


And,



AC = AB = 4×13 = 52 cm
