What is a diagonal formula of a rectangle?
79. What is a diagonal formula of a rectangle?
- D²= √(L²+W²)
- D²=L²*W²
- D²=L²+W²
- D²=L²/W²
Answer
The correct answer is: A) D²= √(L²+W²)
Explanation
The diagonal formula of a rectangle can be determined using the Pythagorean theorem, which connects the sides of a right triangle to the length and width of the rectangle as "L" and "W", respectively. The Pythagorean theorem can be used to compute the diagonal "D" as follows:
D² = L² + W²
To calculate the length of the diagonal "D," multiply both sides of the equation by the square root:
D = √(L² + W²)
