The area of a kite helps us measure how much two-dimensional space lies inside a kite-shaped quadrilateral. This shape has two pairs of adjacent equal sides, making it unique and easy to identify in geometry. The formula for finding its area is simple and highly useful in both academic and real-life situations. Whether you are solving questions for CUET, SSC, Banking, JEE, or dealing with land measurement, knowing this formula saves time and avoids confusion.
Formula for Calculating the Area of a Kite Overview
| Formula | Variables & Meaning | When It Is Used |
|---|---|---|
| Area = ½ × d1 × d2 | d1 = first diagonal, d2 = second diagonal | When diagonals of the kite are known |
What is the Area of a Kite in Maths?
In mathematics, the area of a kite refers to the total two-dimensional space enclosed within a kite-shaped figure. A kite is a quadrilateral with two pairs of adjoining equal sides, and its diagonals intersect at right angles. Because of this perpendicular intersection, the formula for its area becomes very straightforward.
To calculate the area, simply multiply the lengths of the two diagonals and divide by 2. The reason this formula works is that the diagonals divide the kite into two congruent triangles. Since the diagonals act like the height and base of these triangles, finding the area becomes quick and efficient.
This formula is used in real-world tasks such as designing kites, planning land regions shaped like kites, and solving various geometry and mensuration problems. In competitive exams like CUET, SSC, Banking, and JEE, kite area questions frequently appear, and understanding the formula ensures quick scoring.
Examples to Calculate Area of a Kite
Example 1: d1 = 12 cm, d2 = 8 cm
Step 1: Formula = ½ × d1 × d2
Step 2: Area = ½ × 12 × 8
Step 3: Area = 48 cm²
So, the area of the kite is 48 cm².
Example 2: d1 = 15 cm, d2 = 10 cm
Step 1: Formula = ½ × d1 × d2
Step 2: Area = ½ × 15 × 10
Step 3: Area = 75 cm²
So, the area of the kite is 75 cm².
