(A) 4.5
(B) 9
(C) 18
(D) 36
(E) 72
Kudos for the right answer and explanation
Question part of the project GRE Quantitative Reasoning Daily Challenge - (2021) EDITIONGRE - Math BookHere's a sketch of the triangle:

From here, we can see that the base has length
6, and the height is
6
Area = (
base)(
height)/2
= (
6)(
6)/2
= 36/2
= 18
= C
