Question

two equal sides of a triangle is 4 meter less than the third side is the perimeter of the triangle is 70 metre find the length of its side​

Answer 1

Let the 3rd side be x m.

As given, the length of equal two sides = (x-4) m.

Perimeter of the triangle = 70 m

So we can write the equation,

(x-4)+(x-4)+x = 70

or, 3x-8 = 70

or, 3x = 70+8

or, 3x = 78

or, x = 78/3

or, x = 26

So, 3rd side = x m = 26 m.

Equal two sides = (x-4)m = (26-4) m = 22 m.

Hence, the length of its sides are 22 m, 22 m and 26 m.
