Area of a Kite Diamond
A decorative diamond kite has perpendicular supports (diagonals) of 24 inches and 10 inches. Find its surface area.
- Step 1: Identify diagonals: d1 = 24, d2 = 10.
- Step 2: Multiply the diagonals: 24 * 10 = 240.
- Step 3: Divide by 2: 240 / 2 = 120 square inches.
- Step 4: The surface area of the kite is 120 square inches.
Frequently Asked Questions
What makes a parallelogram a rhombus?
A rhombus is a special parallelogram where all four sides are exactly equal in length.
How do you find side length from diagonals?
Since diagonals of a rhombus intersect at 90-degree angles, you can solve the side length using the Pythagorean theorem: side = √((d1/2)² + (d2/2)¹).
Does a rhombus have equal diagonals?
Only if the rhombus is a perfect square. Otherwise, one diagonal is always longer than the other.
