Solved Example on Kite
Ques: Find the area of the kite. Measurements shown are in cm. [Given x = 12 and y = 16.]
Choices:
A. 168 cm^{2}B. 336 cm^{2}
C. 240 cm^{2}
D. 264 cm^{2}
Correct Answer: B
Solution:

Step 1: Triangle ABE is a right triangle. [Diagonals of a kite are perpendicular.]
Step 2: Area of the triangle ABE = 1/2 x 12 x 16 = 96cm^{2}
Step 3: Area of the triangle ACE = Area of the triangle ABE = 96 cm^{2} [?ABE and ?AEC are congruent triangles.]
Step 4: Triangle BED is a right triangle. [Diagonals of a kite are perpendicular.]
Step 5: Area of the triangle BED =1/2 x 12 x 12 = 72cm^{2}
Step 6: Area of the triangle DEC = Area of the triangle BED = 72 cm^{2}. [Triangle BED and Triangle CED are congruent triangles.]
Step 7: Area of kite = Area of triangle ABE + Area of triangle ACE + Area of triangle BED + Area of the triangle CED = 96 + 96 + 72 + 72 = 336 cm^{2}.
