Question
The diagonals of a rhombus are 12 cm and 9 cm long. Calculate the length of one side of a rhombus?
Hint:
eorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°.
If a is the perpendicular, b is the base, and c is the hypotenuse, then according to the definition, the Pythagoras Theorem formula is given as
c2= a2 + b2
The correct answer is: Hence, the length of the side of the rhombus is 7.5 cm.
Applying Pythagoras theorem in △AOB
AB2 = OA2 + OB2
AB2 = 62 + 4.52
AB2 = 56.25
Final Answer:
Hence, the length of the side of the rhombus is 7.5 cm.
