Question 167242
A 100% increase means it is doubled
If the sides of the rectangle are {{{x}}}
and {{{y}}}, the area, {{{A}}} is
(1) {{{A[1] = xy}}}
Doubling each side gives me
{{{A[2] = 2x*2y}}}
(2) {{{A[2] = 4xy}}}
Comparing (1) and (2),
{{{A[2] = 4A[1]}}}
If the dimensions of a rectagle are increased 100%,
The area is increased 400%
