Having a bit of dificulty understanding the wording of the question, but here goes:

gradient of radius line from 0,0 to 4,3 = 3/4

gradient of tangent therefore is -3/4

substituting y = mx + b to get y intersect

3 = -3/4 (4) + b
b = 6

substituting y = 0 to get x intersect

0 = -3/4x + 6
x = 4/3(6) = 8

therefore area = 1/2(8) * 6 = 24
