alleryFormulae of elementary geometry cannot find areas enclosed by:
ACurves
BSquares
CCircles
DTriangl
Answer & Solution
Correct answer: A. Curves
1. Simple shapes have known area formulae.
2. A general curved boundary has none.
3. So elementary geometry is inadequate for areas enclosed by curves.
4. The answer is curves.
