Question

Area of any triangle will be doubled if

• A. Base be doubled
• B. Each side is doubled
• C. Height is doubled
• D. Both base and height are doubled

Answer 1

Answer: (A), (C)

Height is doubled
Base be doubled

Area of the Triangle $\Delta =\frac{1}{2}\times base\times height$

Thus, Area of the triangle $\propto Base$ and Area of triangle $\propto height$.

So, area of triangle is proportional to base as well as height.

Hence, it will be doubled if either base or height is doubled.
