The longer side of a rectangle is three times the length of shorter side. If the length of the diagonal is 10 cm, find the dimensions of the rectangle.

Respuesta :

Answer:

root 10, 3 root 10

Step-by-step explanation:

Let the length of the shorter side be x

Hence,

the length of the longer side= 3x

Length of the diagonal= 10 cm

We know that the sides of the triangle intersect at right angles...

Hence,

By using the pythagoreas property...

[tex] {x}^{2} + {(3x)}^{2} = {10}^{2} \\ {x}^{2} + 9 {x}^{2} = 100 \\ 10 {x}^{2} = 100 \\ {x}^{2} = 10 \\ x = \sqrt{10} [/tex]

Hence,

length of the shorter side=

[tex] \sqrt{10} [/tex]

The length of the longer side =

[tex]3 \sqrt{10} [/tex]
