Question 239340
{{{AreaOfrectangle = Length * Width}}}
Let L be the original Length and W be the original Width.
The original rectangle is then {{{Area=L*W = LW}}}
The new rectangle has Length={{{1.3L}}} and a Width={{{0.7W}}}
{{{NewArea = 1.3L * 0.7W}}} = {{{1.3*0.7LW}}} = {{{0.91LW}}}
So the new area is 91% as large as the original (that is it is 9% smaller in area)
