Question

a man is putting a fenxe around his rectangular yard. his lot measures 13.5 ft long and 47.75 ft wide. the fencing comes in rolls that are 50 ft long. how many numbers of rolls does he need to buy

Answer 1

number of rolls needed = 3

Step-by-step explanation:

length of lot = 13.5 ft

width of lot = 47.75 ft

Since the man is putting a fence round, we would find the perimter of the lot:

perimeter of rectangle = 2(length + width)

perimeter of rectangle = 2(13.5 + 47.75) = 2(61.25)

perimeter of rectangle = 122.5ft

Length of rolls = 50 ft

Number of rolls needed = perimeter of rectangle/length of rolls

Number of rolls needed = 122.5/50 = 2.45

To the nearest whole number, number of rolls needed = 3
