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?

Answer 1

Perimeter = 1 unit

Explanation:

`length \ is \ a \ fraction \ 2 \ over \ 3 = (2)/(3)\\\\Width \ is \ a \ fraction \ 1 \ over \ 3 = (1)/(3)\\\\Perimeter = 2 ( l + w)\\`

`= 2 * ((2)/(3) + (1)/(3)) \\\\=2 * ((3)/(3))\\\\= 1 unit`
