Question

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 3 unit and the width is Fraction 1 over 3 unit, what is the perimeter of the rectangle in units? (3 points)

Answer 2

2

Explanation:

2[2\3±1\3]

2×2\3=4\3

2×1\3=2\3

4\3±2\3=6\3

6\3 is the same as 2 because if you divide 6 by 2 you will get 2

so the answer is 2
