Question

The diagonals AC and BD of rectangle ABCD intersect in point K. If l(AK) = 3.5 cm, then l(KC) = ? and l(AC) = ?

Answer 1

Answer:

KC = 3.5 cm

AC = 7 cm

Step-by-step explanation:

ABCD is a rectangle

& AC & BD are diagonals intersecting at point K

Now diagonals of a rectangle bisect each other

=> AK = CK  

AK = 3.5 cm given

=> KC = CK = AK = 3.5 cm

=> KC = 3.5 cm

AC = AK + CK

=> AC = 3.5 + 3.5

=> AC = 7 cm
