Question

Find the length of the diagonal of the rectangle.

Answer 1

Answer:

≈ 11.4 m

Step-by-step explanation:

The diagonal splits the rectangle into 2 right triangles , with legs 7 and 9 and the diagonal the hypotenuse.

Using Pythagoras' identity with h as the diagonal, then

h² = 7² + 9² = 49 + 81 = 130 ( take the square root of both sides )

h = $\sqrt{130}$ ≈ 11.4 m ( to the nearest tenth )
