Question

ABCD is a rectangle whose three vertices are B(4, 0), C(4, 3) and D(0, 3). The length of one of its diagonals is : (B) 6 units (C) 6.5 units (D) 7 units (A) 5 units​

Answer 1

Length of Diagonal of rectangle ABCD = (for figure .. refer to attachment)

$BD = \sqrt{(0 - 4) {}^{2} + (3 - 0) {}^{2} }$

$BD = \sqrt{4 {}^{2} + 3 {}^{2} }$

$BD \sqrt{16 + 3}$

$BD = \sqrt{25}$

$BD = 5 \: units...$

therefore option (A) 5 units is the answer.
