HELPPPPPPPPP PLEASEEEEEEEEEEEEEEEEEE






The expression 2(l + w) is used to calculate the perimeter of a rectangle, where l is length and w is width. If the length is Fraction 2 over 7 unit and the width is Fraction 3 over 7 unit, what is the perimeter of the rectangle in units?

Fraction 5 over 7 unit
1 unit
1Fraction 3 over 7 units
2Fraction 5 over 7 units

Answer 1

Answer:

1 3/7, or "1Fraction 3 over 7 units"

Step-by-step explanation:

2(l+w) where l = 2/7 and w = 3/7. You would do 2/7+3/7 = 5/7.

Then, multiply 2(5/7) = 10/7. If you simplify the improper fraction, you end up with 1 3/7 as an answer.

Hope this helped! :)

Answer 2

1 3/7 1 3/7 or one fraction 3 over 7
