Answer 1

First, calculate the area of the triangle.  A=1/2bh.  The base is the length of CB (4) and the height is the length from A to the bottom (3):

A=(1/2)(3)(4)

A=6

Now, see which of the choices has an area of 6.

A:

The area of a square is A=s^2.  A=4^2=16.  16*2=32

B:

A=4^2=16.  16*(1/2)=8

C:

The area of a rectangle is A=lw.  A=4(3)=12.  12(1/2)=6

D:

A=4(3)=12.  12*2=48

C.
