If ABCD is a rectangle, what is the area of the triangle PQR?
(Statement1): DQ = QR = RC
—> nothing tells us about the rectangular
Insufficient
(2) The area of rectangle is 38 square centimetres
No info about the triangle.
Insufficient
Taken together 1&2,
ab= 38
—> the area of the triangle:
(a* b/3)/2= (a*b)/6 = 38/6= 19/3
Sufficient
The answer is C

Divide the rectangle into triangles
By imaginary lines.
AD/BCE
Now first is insufficient as we don’t know at least one length
So BCE
Now second option alone cannot help us answer.
But together yes sufficient
So C
