James is fencing a rectangular field that measures 25 ft by 21 ft. How much fencing should he buy?

I am not asking for the answer, just help! I know that you find the are of a rectangle by multiplying its length times width.....so is that how you get the answer? I know this is basic but I suck at math.|||The rectangle has four sides...2 sides are 25ft and 2 sides are 21ft...So to figure out the linear feet James needs to buy, simply add 25+25+21+21 and the answer is how much fence he needs.





EDIT: Multiping 25 x 21 will give you the square footage not the linear feet.|||Find the Perimeter of the rectangle.Thats the total fencing to buy


P=2(L+b)


P=2(25+21)


P=2*46=92 Ft|||people are giving you conflicting answers. just think about this... does the fence need to cover the perimeter or the whole area of the rectangle?|||Yes, that is how you get the answer.|||Indeed, the area (in square feet) = L x W.





However, to determine the length of fencing that James needs to buy, you would need to calculate the perimeter of the field.





Perimeter = 2L + 2W





2(25) + 2(21) = 50 + 42 = 92 ft





These are linear (not square) feet.|||yes thats how dude
