Math Problem Statement
The foundation of a building is in the shape of a rectangle, with a length of 20 meters (m) and a width of 18 m.To the nearest meter, what is the distance from the top left corner of the foundation to the bottom right corner?
Solution
The problem asks for the distance from the top left corner of the rectangle to the bottom right corner. This distance corresponds to the diagonal of the rectangle. To calculate the diagonal of a rectangle, we use the Pythagorean theorem:
Where:
- is the diagonal (distance from top left to bottom right),
- is the length of the rectangle,
- is the width of the rectangle.
Step-by-Step Solution:
-
Substitute the given values:
-
Calculate the squares of the length and width:
-
Add the squares:
-
Take the square root of the sum:
-
Round to the nearest meter:
Final Answer:
The distance from the top left corner to the bottom right corner of the foundation is approximately 27 meters.
