Solution
The correct option is B5 Let the points be A(0,0)B(4,0),C(4,3),D(0,3) So, the length of the diagonal will be distance between A and C. Distance between two points (x1,y1) and (x2,y2) can be calculated using the formula √(x2−x1)2+(y2−y1)2 Hence, Length of diagonal AC =√(4−0)2+(3−0)2=√16+9=√25=5
