Perimeter = 2( Length + Width)

<em>Given that Perimeter = 3 1/12 feet and Width = 2/3 foot, plug the values into the formula to find the length:</em>

3 1/12 = 2( Length + 2/3)

3 1/12 = 2Length + 4/3

2 Length = 3 1/12 - 4/3 

2 Length = 7/4

Length = 7/4 ÷ 2 

Length = 7/4 x 1/2 

Length = 7/8

<em>Now that we know the length is 7/8 and the width is 2/3, find the area:</em>

Area = Length x Width 

Area = (7/8)(2/3) = 7/12

Answer: Area = 7/12 ft²

Anais bought yards of ribbon. she had feet inches of ribbon left after trimming some curtains. how many inches of ribbon did ana

<u>Anais bought </u><u>2 1/2 yards</u><u> of ribbon. She had </u><u>2 feet 8 inches</u><u> of ribbon left after trimming some curtains. Anais uses 58 inches of ribbon to trim the curtains.</u>

What is Unit Conversion?

  • Conversion of one unit to another unit of measurement for the same quantity using multiplication/division by conversion factors is known as unit conversion.
  • The units are expressed using scientific notation and converted into numerical values as per the quantities.

Anais bought 2 1/2 yards of ribbon.

And she had 2 feet 8 inches left after trimming some curtains.

The first thing to do is to convert all units to inches;

From standard conversion rate.

1 yard  = 36 inches

As such  2 1/2 yards of ribbon in inches will be:

= 2 1/2 × 36 inches

= 5/2 × 36 inches

= 5 × 18 inches

= 90 inches of ribbon bought.

Similarly, since 1 foot  = 12 inches.

The amount of curtains left after trimming is:

= ( ( 2 × 12 ) + 8 )inches

= (24 + 8) inches

= 32 inches

If Anais bought 90 inches of ribbon and she had 32 inches of ribbon left after trimming some curtains.

It implies that the number of inches of ribbon that Anais used is:

= 90 inches - 32 inches

= 58 inches

Therefore, we can conclude that Anais used 58 inches of ribbon.
