ABCD is a rectangle whose three vertices are B (4,0), C (4,3) and D (0, 3).
In Rectangle ABCD , BD is a diagonal .
By Using Distance Formula,
In BD,
x1 = 4, x2 = 0 , y1 = 0 , y2 = 3
BD = √(x2 – x1)² + (y2 – y1)²
BD = √(0 – 4)² + (3 – 0)²
BD = √4² + 3²
BD = √16 + 9
BD = √25
BD = 5 units
Length of the diagonal is 5 units
