The equation for the area of a rectangle is: A = bh, where A = area, b = length of base, and h = height.
You're told that the base, b = 5 in, and the height, h = 2.5 in. Plug these numbers into the equation to find the area:
A = bh
A = (5)(2.5)
A = 12.5 [tex]in^2[/tex]
If you include the hundredth place, your answer would be 12.50 [tex]in^2[/tex].
