Question

The perimeter of a triangle is 65 meters. The second side is 5 less than the first side. The thrid side is 7 meter more than the first side. What is the lenght of each side?

Answer 1

Hii friend,

Let the Length of first side be X m

Then the Length of second side will be (X-5) m

And,

The third side will be (X+7) m.

Perimeter of the triangle = 65

X+ X - 5 + X + 7 = 65

3X +2 = 65

3X = 65-2

X = 63/3

X = 21 m

Therefore,

Length of first side=X = 21 m

Length of second side = X-5 = 21-5 = 16 m

Length of third side = X+7 = 21+7 = 28 m.

HOPE IT WILL HELP YOU..... :-)
