the remains of an ancient ball court include a rectangular playing alley with a perimeter of about 64 M. the length of the alley is 2 times the width. find the length and the width of the playing alley​

Respuesta :

Answer:

[tex]Length = \frac{64}{3}m[/tex]

[tex]Width= \frac{32}{3}m[/tex]

Step-by-step explanation:

Given

[tex]Perimeter = 64m[/tex]

[tex]Length = 2 * Width[/tex]

Required

Determine the length and the width

Since the alley is rectangular, the perimeter is as follows;

[tex]Perimeter = 2 (Length * Width)[/tex]

Substitute 64m for Perimeter

[tex]64m = 2(Length + Width)[/tex]

Substitute 2 * Width for Length

[tex]64m = 2(Width+ 2 * Width)[/tex]

[tex]64m = 2(Width+ 2 Width)[/tex]

[tex]64m = 2(3 Width)[/tex]

[tex]64m = 6Width[/tex]

Divide both sides by 6

[tex]Width= \frac{64m}{6}[/tex]

[tex]Width= \frac{32}{3}m[/tex]

Recall that

[tex]Length = 2 * Width[/tex]

[tex]Length = 2 * \frac{32}{3}m[/tex]

[tex]Length = \frac{64}{3}m[/tex]
