The perimeter is basically the outline of the shape. The perimeter of a rectangle is given by P=2l+2w, where l is the length and w is the width. Thus, the perimeter of the flower bed would be given by P=2(3n5o)+2(5n5o).
About 37% because 865/2330 is .3712446352. To find the percent, you move the decimal right two spaces. In your case, you would round to the nearest whole, which is 37%.
