1 answer:
Setler [38]3 years ago
7 0

Answer:

x = 6

Step-by-step explanation:

The scale factor is

28/8 = 7/2

We take the ratio of the larger side over the smaller side

Using ratios we can find the sides

28         21

----- = ---------

8           x

Using cross products

28x = 21*8

28x =168

Divide each side by 28

28x/28 = 168/28

x =6

richie has a rug in his bedroom with a perimeter of 42 feet. the length of the rug is 12 feet what is the width of the rug
Usimov [2.4K]

The width of the rug is 9 feet.

Step-by-step explanation:

Perimeter of rug = 42 feet

Lengths are same in square and rectangle shapes; therefore;

Length of rug = 12 feet

Width of rug = w

Perimeter = Length + Length + Width + Width

Perimeter = 12+12+w+w

42=24+2w\\42-24=2w\\18=2w\\2w=18

Dividing both sides by 2

\frac{2w}{2}=\frac{18}{2}\\w=9

The width of the rug is 9 feet.

Keywords: perimeter, division

• Assuming the two horizontal likes are h & l (pic cut off)
• 62 = 6y - 142
• y = 34 degrees
• 180 degrees = straight line
• Because of how things are drawn, 62 + x = 180
• x = 118 degrees
• Check our work: 118 * 2 + 62 * 2 = 360 degrees
