# Calculate the Diagonal of a Rectangle

**Operation: ** Diagonal of a Rectangle

**Instruction: **To find the diagonal (d) of a rectangle, use the lengths of its sides (a and b), and apply them in the formula.

**Formula: ** sqrt(pow(a, 2) + pow(b, 2))

**Example:** If side a = 8 units and side b = 6 units, then d = sqrt(pow(8, 2) + pow(6, 2)) ≈ 10 units

Result:
