astraxan [27]

Answer:

8 inches

Step-by-step explanation:

Let w be the width of rectangle B.

Since, both rectangles are similar.

Therefore, corresponding lengths and widths of rectangles A and B will be in proportion.

$\therefore \frac{20}{40} = \frac{4}{w} \\ \\ \frac{1}{2} = \frac{4}{w} \\ \\ w = 2 \times 4 \\ \\ w = 8 \: inches$

What is the area of a rectangle with side lengths 2/5 feet and 4/6 feet?

kotegsom [21]

Answer:

$\frac{4}{15}$ (4/15)

Step-by-step explanation:

$\frac{4}{6}=\frac{2}{3}$

$\frac{2}{5}*\frac{2}{3};$

1- Multiply the numerators:

$2*2=4$

2- Multiply the denominators:

$5*3=15$

3- Thus:

$\frac{2}{5}*\frac{2}{3}= \frac{4}{15}$

Hope this helps ;)
