Question

The area of a rectangle with 2 1/2 as the width and 10 feet as the length

Answer 1

The formula for the area of a rectangle is:
$A=wl$
w = width
l = length

First, we have to convert 2 $\frac{1}{2}$ into an improper fraction, then into a number. The improper fraction would be $\frac{5}{2}$. Let's convert that into a decimal.
$5/2=2.5$

Let's multiply
$2.5*10=25$
The area of the rectangle would be 25 feet!
