Given :- if the length of one diagonal and one side of a rhombus are 24cm and 15 cms respectively then find the length of other diagonal ?
Solution :-
given that,
→ One diagonal of rhombus = 24 cm
→ Side of rhombus = 15 cm .
since we know that,
- all sides of rhombus are equal .
- Diagonal bisect each other at 90° .
Let length of other diagonal is 2x cm .
then,
→ x² + (24/2)² = 15² { By pythagoras theorem.}
→ x² + 144 = 225
→ x² = 225 - 144
→ x² = 81
→ x = 9
then,
→ Length of other diagonal = 2x = 2 * 9 = 18 cm (Ans.)
