Question 204867
Assuming that the 15 feet you mention is the diameter (D) of the semicircular areas, then the perimeter of the flower consists of two sides of the square (15ft.+15ft. = 30 ft.) plus the circumference of the circle (2 semicircles) which is {{{(pi)*D}}} and if we use {{{pi = 3.14159}}} as an approximation, then we have:
{{{P = 15+15+15(3.14159)}}}
{{{P = 30+47.1238}}}
{{{highlight(P =77.124)}}}feet.
