A rectangular lawn has a diagonal path
The lawn is 10 m wide and 15 m long,
Work out the length of the path.
Give your answer in surd form

Respuesta :

The length of diagonal path is: 5√13

Step-by-step explanation:

Given

Length of lawn = l = 15m

Width of lawn = w = 10m

The diagonal of a rectangle divides the rectangle in two right angled-triangles in which the diagonal is the hypotenuse and width will be base and length will be perpendicular.

So we can use the Pythagoras theorem to find the length of diagonal

[tex]H^2 = B^2+P^2\\[/tex]

Let d be the diagonal

Putting the values

[tex]d^2 = w^2+l^2\\d^2 = (10)^2+(15)^2\\d^2 = 100 + 225\\d^2 = 325\\[/tex]

Taking square root on both sides

[tex]\sqrt{d^2} = \sqrt{325}\\d = \sqrt{25*13}\\d = \sqrt{5^2*13}\\d = 5\sqrt{13}[/tex]

The length of diagonal path is: 5√13
