Question 485339

given:

{{{A=16 *2ft^2=32ft^2}}}......so, one side is {{{a=16}}} and other side is {{{b=2}}}


If one side {{{a=16ft}}}is made {{{4in=0.3ft}}} longer we will have {{{a=16ft-0.3ft=15.7ft}}}


and if the other side {{{b=2}}} is made {{{2in= 0.17ft }}} shorter we will have 

{{{b=2ft-0.17ft=1.83ft}}}

than area will be

{{{A=15.7 *1.83ft^2=28.73ft^2}}}
