For this case we assume that the photo album is rectangular in shape and therefore the fabric too. By definition, the area of a rectangle is given by:

$A = a * b$

Where:

a: It is the length of the rectangle

b: It is the width of the rectangle

According to the problem data we have to:

$b =\frac {5}{8} \yard\\A = \frac {5} {16} \ yards ^ 2$

Substituting:

$\frac {5} {16} = a * \frac {5} {8}$

We clear "a":

$a = \frac {\frac {5} {16}} {\frac {5} {8}}\\a = \frac {5 * 8} {16 * 5}\\a = \frac {8} {16}\\a = \frac {1} {2}$

Thus, the length of the fabric is $\frac {1} {2} yards.$

ANswer:

The length of the fabric is $\frac {1} {2} yards.$

Explain how knowing 50×4 helps you find 500×400

Andre45 [30]

5x4= 20
50x40=200
500x400=200000
Do you see the pattern? 5x4=20, which means that all you need to do is add the zeros. 50x40 has two zeros, which means it should equal 200.
