We need the value of the following parameters in order to determine the area of a triangle:
a) Length of three sides
b) Length of base and height

St1:- b – f = 0 and a – e = –4
Only measure of base is known.
base=a+4-a=4 unit
Measure of height is in dark.
Insufficient.

St2:- f – d = –3 and c – e = –2
Only measure of height is known.
Height=f+3-f=3 unit
Measure of base is in dark.
Insufficient.

Combined, measure of both base and height is known. Area can be calculated. (For reference, combining st1 & 2, vertices of the triangle become Left(a,b),Right(a+4,b), Top(a+2,b+3) and the coordinate intersection of base and height is (a+2,b))
Sufficient.

Ans. (C)

(1) b – f = 0 and a – e = –4
given that the base is parallel to x axis

area = \(\frac{b * h}{2}\)
b= difference in x co ordinates = 4 ( a-e)
h=difference in y co ordinates = ?

insufficient

(2) f – d = –3 and c – e = –2
b= difference in x co ordinates = ?
h=difference in y co ordinates = f-d=3

insufficient.

using both the statements

area = \(\frac{4*3}{2}\)= 6
sufficient
C
