Answer:
Let's start by using the information given in the problem to write an equation for the perimeter of the rectangle:
Perimeter = 2(length + width)
We know that the length of the rectangle is twice its width, so we can write:
length = 2*width
Substituting this expression into the equation for the perimeter, we get:
Perimeter = 2(2*width + width)
Simplifying this expression, we get:
Perimeter = 6*width
We are given that the perimeter is 7 1/3 cm, which we can convert to a mixed number:
Perimeter = 7 + 1/3 = 22/3
Substituting this value into the equation above, we get:
22/3 = 6*width
Solving for the width, we get:
width = 22/3 ÷ 6 = 11/9
Now that we have the width, we can use the expression for the length to find its value:
length = 2*width = 2(11/9) = 22/9
Finally, we can use the formula for the area of a rectangle, A = length * width, to find the area:
A = (22/9) * (11/9) = 242/81 square cm
Therefore, the area of the rectangle is 242/81 square cm.
