Understanding the Basics of a Rhombus

A rhombus is a type of polygon that has four equal sides. It is a special type of quadrilateral where all four sides are of equal length. One of the key properties of a rhombus is that its diagonals bisect each other at right angles. This means that the diagonals of a rhombus intersect each other at their midpoints, forming four right-angled triangles.

Calculating the Area of a Rhombus

The area of a rhombus can be calculated using the formula:

Area = (d1 x d2) / 2

where d1 and d2 are the lengths of the diagonals.

In this problem, we are given the lengths of the diagonals as 14 cm and 11 cm. We can use these values to calculate the area of the rhombus.

Calculating the Area

To calculate the area of the rhombus, we need to multiply the lengths of the diagonals and then divide the result by 2.

Area = (14 x 11) / 2 Area = 154 / 2 Area = 77 cm²

Therefore, the area of the rhombus is 77 cm².

The Length of One of Its Diagonals is 18 cm

However, we are also given that the length of one of its diagonals is 18 cm. This means that the length of the other diagonal is not 11 cm, but rather 18 cm is not the diagonal, but the length of one of the sides of the rhombus.

Calculating the Length of the Other Diagonal

Since the diagonals of a rhombus bisect each other at right angles, we can use the Pythagorean theorem to calculate the length of the other diagonal.

Let's call the length of the other diagonal "d2". We can use the Pythagorean theorem to calculate d2:

d2² = 18² - 11² d2² = 324 - 121 d2² = 203 d2 = √203 d2 ≈ 14.27 cm

Therefore, the length of the other diagonal is approximately 14.27 cm.

Calculating the Area of the Rhombus

Now that we have the lengths of both diagonals, we can calculate the area of the rhombus:

Area = (14.27 x 11) / 2 Area ≈ 78.35 cm²

Therefore, the area of the rhombus is approximately 78.35 cm².

Conclusion

In conclusion, the area of the rhombus with diagonals 14 cm and 11 cm is 77 cm². However, if the length of one of its diagonals is 18 cm, then the area of the rhombus is approximately 78.35 cm².

The Final Answer

The final answer is 77 cm².
