The area and a diagonal of a rhombus are 60 cm\(^2\) and 12 cm respectively. Calculate the length of the other diagonal.
Answer Details
The area of a rhombus is half the product of the lengths of its diagonals. Therefore, if we know the area of the rhombus and one of its diagonals, we can use this formula to find the length of the other diagonal.
Let's call the length of the first diagonal 12 cm, and let's call the length of the other diagonal d cm. The area of the rhombus is given as 60 cm\(^2\). We can write the formula for the area of a rhombus as:
Area = (1/2) x (diagonal 1) x (diagonal 2)
Substituting the values we know, we get:
60 = (1/2) x 12 x d
Simplifying this equation, we get:
60 = 6d
Dividing both sides by 6, we get:
d = 10
Therefore, the length of the other diagonal is 10 cm.
So, the answer is option C - 10cm.
