The width of a rectangle is 6 2/3 inches. The length of the is twice it’s width. What so the perimeter of the rectangle?
Nookie1986 [14]
\text {Width = }  6\dfrac{2}{3}  \text { inches}



The length is twice its width:
\text {Length = } 2 \times 6\dfrac{2}{3} \text { inches}

Change to improper fraction:
\text {Length = }2 \times \dfrac{20}{3} \text { inches}

Combine into single fraction:
\text {Length = } \dfrac{40}{3} \text { inches}


Find Perimeter :
\text {Perimeter = Length + Length + Width + Width}

\text {Perimeter = } \dfrac{40}{3} + \dfrac{40}{3}   + \dfrac{20}{3}   + \dfrac{20}{3} = \dfrac{120}{3}  = 40 \text { inches}


\bf \text {Answer: Perimeter =  40 inches}

I don’t Understand this who can help me
harina [27]

Step-by-step explanation:

The area of a square is

{s}^{2}

where s is the side length.

It is given that the smaller square side length is s so that means the area of that smaller square is the formula above.

The longer square is twice the side length of the side length of the smaller square.

Since all squares have equal sides, that means all the side are twice than the smaller square sides.

We can represent that larger square area by

(4s) squared

To find how many smaller squares it would take to fill the larger square divide the formula by each other.

(4s)÷s squared =4
