Question

each of equal side of an isosceles triangle is four time the third side. the perimeter of the triangle is 117 cm find the sides of triangle

Answer 1

Let the third side be x.

Then two equal sides are 4x.

Since Perimeter of triangle = Sum of all sides

=) x + 4x + 4x = 117cm

=) 9x = 117cm

=) x = 117/9cm

=) x = 13cm

Hence sides are 13cm , 4*13cm and 4*13cm.

= 13cm,52cm and 52cm.
