Question 478146
the length of rectangle B is 50% longer than the than the length of rectangle A 
and the width of rectangle B is 50% shorter than the width of rectangle A.
what is the ratio between the area of rectangle B and the area of rectangle A?
:
Let L = Length of A
Let W = Width of A
then
LW = area of A
and
1.5L = Length of B
.5W = Width of B
then
1.5L*.5W = .75LW, the area of B
:
Ratio: {{{(LW)/(.75LW)}}}
Cancel LW, make it into integers
{{{1/.75}}} * {{{4/4}}} = {{{4/3}}} is A to B Ratio
4:3 is the area of B to A
