Question 555830
{{{P=2L+2W}}} Start with the perimeter of a rectangle formula.



{{{P=2(15)+2(8)}}} Plug in {{{L=15}}} and {{{W=8}}}.



{{{P=30+2(8)}}} Multiply {{{2}}} and {{{15}}} to get {{{30}}}.



{{{P=30+16}}} Multiply {{{2}}} and {{{8}}} to get {{{16}}}.



{{{P=46}}} Add {{{30}}} to {{{16}}} to get {{{46}}}.



So the perimeter is {{{46}}} units.
