Question

Length of equal side of a triangle is 4m less from the third side.If the perimeter of triangle is 55m.Find the dimensions of the tiangle.

Answer 1

Answer:

21, 17 and 17.

Step-by-step explanation:

Let the length of the third side = X

⇒ The length of the other two equal sides = X - 4

Perimeter of the triangle = X + (X - 4) + (X - 4) = 55

⇒ 3X - 8 = 55

⇒ 3X = 63

⇒ X = 21

and X - 4 = 17

Hence, the three sides are 21, 17 and 17.
