A)The quantity in Column A is greater.
B)The quantity in Column B is greater.
C)The two quantities are equal.
D)The relationship cannot be determined from the information given.
Col. A: \(\frac{1}{2}(PR)(4)\)
Col. B: \(\frac{1}{2}(PR)(2)\)
Dividing both sides with \(\frac{1}{2}(PR)\);
Col. A: 4
Col. B: 2
Hence, option A

Since both the triangles have the same base
let base be b
QA:
Area of prs = 1/2 * b*4 = 2b
QB:
Area of pqr = 1/2 * b *2 = b
since the base is same so QA=2 and QB=1
Option (A)
why the answer is given C
