(a) The area of a rectangle with length 20 and width
(b) The area of a rectangle with length 10 and width
(a) and (b) are equal
(b) is the greater quantity
(a) is the greater quantity
It is impossible to determine which is greater from the information given
(a) is the greater quantity
The area of a rectangle is the product of its length and its width.
The rectangle described in (a) has area
The rectangle described in (b) has area
, and is positive, so , and . The rectangle from (a) has the greater area.
Note that the value of has no bearing on the answer, except for the fact that it is positive.

We can fill in a few edge lengths below:
All six sides are rectangles, so their areas are equal to the products of their dimensions. We specifically notice that the top, bottom. front, and back each have area . Since the total of these four areas is . Since the left and right sides have not been included, the total surface area must be more than .
Example Question #511 : Isee Middle Level (Grades 7 8) Quantitative Reasoning
What is the area of the figure below?
To find the area of the figure above, we need to split the figure into two rectangles.
