If a rectangular garden is 40 ft by 45 ft, how many feet of fence are needed to enclose it

Question

Math word problem that are really difficult for me 

Answer 1

170ft are needed

 

you just have to add 40+40+45+45. This will give you the perimeter of the garden which is the amount of fence you need to enclose the garden

Answer 2

Perimeter of the garden = 2( Length + Width)

                                    = 2 ( 40 + 45) = 170 ft to cover the entire garden
