Curt is installing a picket fence around his garden which is 45.45 ft by 14.63 ft. when he gets to the hardware store he finds that each picket fence slat is two feet wide. if curt does not want any spaces between each slat, use estimation to determine how many slats of fencing he should buy.

The fence must have two sides of length 45.45 ft and two sides of length 14.63

To cover each of 45.45 ft long side, he will need 45.45 /  2 = 22.7 slats which approximates to 23. So, they are 2 * 23 = 46 slats.

To cover each of 14.63 ft sides, he will need 14.63 / 2 = 7.3 which approximates to 8 (to not leave any spaces between each slat). So, they are 2 * 8 = 16 slats.

That makes 46 + 16 = 62 slats.

around 62 slats.
