Question

He 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 2 over 3 unit
1 unit
1Fraction 2 over 3 units
2 units

Answer 1

2 Units.

Explanation:

p = 2(l + w)

= 2 (2/3 + 1/3)

= 2 (3/3)

= 2 (1)

= 2

Answer 2

ANSWER

D. 2 units

EXPLANATION

The expressions for the perimeter is;


`P = 2(l + w)`




The length of the rectangle is


`l = (2)/(3 ) \: units`


and the width of the rectangle is,


`w = (1)/(3)`

We substitute these values into the formula to obtain,



`P =2 ( (2)/(3) + (1)/(3) )`

We simplify the equivalent fractions in the bracket to obtain,


`P =2 ( (2 + 1)/(3))`



`P =2 ( (3)/(3))`



`P =2 ( 1)`



`P =2 \: units`
