SAT Subject Test Mathematics Level 1

(Marvins-Underground-K-12) #1

The square above, with sides of length 5, has an area of 5^2 = 25.


POLYGONS—PERIMETER AND AREA


The test makers like to write problems that combine the concepts of
perimeter and area. What you need to remember is that perimeter and area
are not directly related. In Example 5, for instance, you have two figures with
the same perimeter, but that doesn’t mean they have the same area.


SKETCH A FIGURE IF NONE IS PROVIDED


The best    way to  get a   handle  on  a   figureless  geometry    problem is
usually to sketch a figure of your own. You don’t have to be an artist.
Just be neat and clear enough to get the picture.

Example 5

A   square  and a   regular hexagon have    the same    perimeter.  If  the area    of
the square is 2.25, what is the area of the hexagon?

1.


(A) 2.250


(B) 2.598
