Question

pleaaseeeee help 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? Fraction A:2 over 3 unit B:1 unit c:1Fraction 2 over 3 units D: 2 units

Answer 1

$l=\frac{2}{3} \\ w=\frac{1}{3} \\ \\ P=2(l+w)=2(\frac{2}{3}+\frac{1}{3})=2 \times \frac{2+1}{3}=2 \times \frac{3}{3}=2 \times 1=2$

The perimeter is 2 units.
