I just did this test! sigh..

anyways, let's start off with big triangle.

Base = (14,0) and (2,0). Now we know that base is on x-coordinate, therefore 14-2 = 12.

Height of the triangle is (8,12), ycoordinate of 12.

So you have 12 x 12 = 144, then /2 for area of 72.

now, same for small triangle.
base = (10,0) - (6,0) = 4
height = (8,4) = 4
(4x4)/2 = 8

8 to 72
or
1 to 9
Hence, the answer A

Triangle PQR
Base = 4
Height = 4

Triangle LMN
base = 12
ht = 12

ratio of area will be 1:9
