Question 645193

the area of a rectangle is {{{A=a*b}}}


with side lengths of {{{2a/5b}}} units and {{{3b/8}}} units the area of a rectangle will be:

{{{A=(2a/5b)*(3b/8)}}}

{{{A=(2a*3b)/(5b*8)}}}

{{{A=(cross(2)a*3cross(b))/(5cross(b)*cross(8)4)}}}

{{{A=(a*3)/(5*4)}}}

{{{A=3a/20}}}

{{{A=(3/20)a}}}

{{{A=0.15a}}}
