Question

diagonal of a rhombus is 10 cm and 24 cm if perimeter is

Answer 1

If the two diagonals of a rhombus are 10 cm and 25 cm means the perimeter will be 52 and the area will be 17.5 cm sq

Answer 2

Let AC = 24 cm
      BD = 10 cm
diagonals bisect each other at O at right angle.
So AO = 24/2 = 12 cm
     BO = 10/2 = 5 cm
AB = √(5²+12²) = √25+144 = √169 = 13 cm
Perimeter = 4×side = 4×13 = 52 cm
