Answer:
-10-(-3)
Step-by-step explanations
we have-10-(-3). since law of basic operation:
+*+=+
-*-=+
so we have-10(-*-=+)
so we have-10+3
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:

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:

Substituting:

We clear "a":

Thus, the length of the fabric is 
ANswer:
The length of the fabric is
