The correct Answer is:
To determine whether the statement "If the area of a rhombus is 60 cm², then its diagonals are 10 cm and 6 cm long" is true or false, we can use the formula for the area of a rhombus in terms of its diagonals. ### Step 1: Understand the formula for the area of a rhombus The area \( A \) of a rhombus can be calculated using the lengths of its diagonals \( d_1 \) and \( d_2 \) with the formula: \[ A = \frac{1}{2} \times d_1 \times d_2 \] ### Step 2: Substitute the given values into the formula In this case, we are given the area \( A = 60 \, \text{cm}^2 \) and the lengths of the diagonals \( d_1 = 10 \, \text{cm} \) and \( d_2 = 6 \, \text{cm} \). We can substitute these values into the formula: \[ 60 = \frac{1}{2} \times 10 \times 6 \] ### Step 3: Calculate the right-hand side Now, we calculate the right-hand side: \[ \frac{1}{2} \times 10 \times 6 = \frac{60}{2} = 30 \, \text{cm}^2 \] ### Step 4: Compare the calculated area with the given area We find that the calculated area \( 30 \, \text{cm}^2 \) does not equal the given area \( 60 \, \text{cm}^2 \). ### Step 5: Conclusion Since the calculated area does not match the given area, the statement is false. The diagonals of a rhombus with an area of \( 60 \, \text{cm}^2 \) cannot be \( 10 \, \text{cm} \) and \( 6 \, \text{cm} \). ---
