Question

a region is sitting in the xy-plane. all of its linear dimensions are doubled . what is the ratio of the new area to the original area?

Answer 1

the new area is 4 time larger

Answer 2

why? would you mind give me some explanation ?

Answer 3

sure

Answer 4

area is computed using exactly two linear dimensions for all plane figures. Example: area of a rectangle =bh. If the length nd height are doubled, the new area is (2b)(2h)=4bh. i.e., four times larger than the initial area

Answer 5

but if the area is bounded by two curve f(x) and g(x)?
