Answer 1

Answer:

5 cm

Step-by-step explanation:

Let us assume O is the point of intersection of diagonals.

Case 1:

In a rhombus the diagonals bisect each other.

OT = x and OL = x-1 and TL = x+1

By Pythagoras theorem,

(x)² + (x-1)² = (x+1)²

x² + x² - 2x + 1 = x² + 2x + 1

x² - 4x = 0

=> x(x-4) = 0

=> x = o or 4.

Since x cannot be zero, x = 4,

Thus the length of side is 4 + 1 = 5 cm.
