Peter wants to add a room to his house using a ratio of 9 to 4 for its dimensions. He will make the length of the room 17 feet. How wide will the room be to the nearest foot?

Answer :

Answer:

The width of the room to nearest foot [tex]\approx[/tex] 8 feet

Step-by-step explanation:

Ratio of length to width of the room Peter wants to add to his house = 9:4

Given length of the room = 17 feet

To find the width of the room.

Solution:

From the given data we know that the length and width of the room bear a common ratio which is 9:4

Let width of the room in feet be = [tex]w[/tex]

Thus, the ratio can be given as:

⇒ [tex]\frac{Length}{Width}=\frac{9}{4}[/tex]

Plugging in length of room in the equation = 17 feet.

Solving for [tex]w[/tex]

⇒ [tex]\frac{17}{w}=\frac{9}{4}[/tex]

Multiplying both sides by 4.

⇒ [tex]4\times\frac{17}{Width}=\frac{9}{4}\times4[/tex]

⇒ [tex]\frac{68}{w}=9[/tex]

Multiplying both sides by [tex]w[/tex]

⇒ [tex]w\times\frac{68}{w}=9\times w[/tex]

⇒ [tex]68=9w[/tex]

Dividing both sides by 9.

⇒ [tex]\frac{68}{9}=\frac{9w}{9}[/tex]

∴ [tex]w=7.55\approx 8[/tex]

Thus, the width of the room to nearest foot [tex]\approx[/tex] 8 feet
