Question

Jacob made a rectangular table for his dining room. The sides of the table are 16 feet and 5 feet. What is the length of the diagonal of the table?

Answer 1

To find the length of the diagonal, we will use the pythagoras theorem

opposite² + adjacent² = hypotenuse²

let x be the length of the diagonal, which is equal to the hypotenuse

opposite = 16

adjacent = 5

substitute the values into the formula;

16² + 5² = x²

256 + 25 = x²

281 = x²

Take the square root of both-side of the equation

16.76 = x
