Question

Interpret the definite integral A=a~b dA=a~b L(x)dx as computing the area of a region in the xy-plane. Then one can think of the definite integral as:
A. the antiderivative of L(x)
B. "accumulating" all of the small segments of area "dA" from a to b.
C. "accumulating" all of the small segments of area "L(x) x d(x)" from a tob, where L(x) represents the length of a rectangle at a particular xvalue, and dx the width.
D. both "accumulating" all of the small segments of area "dA" from a to bAND "accumulating" all of the small segments of area "L(x) x d(x)" from a to b, where
