The area of Kaitlyn's square garden is 345 square feet. One side of the garden is next to a shed. She wants to put a fence around the other three sides of the garden. Find three sets of approximations for the amount of fence it will take. Then determine how much fence she should buy.
+23251 If the side of a square is x then the area of the square is x2.
In this case: x2 = 345 ---> x = 18.57 (approximately).
Since you need to fence three sides, you need 3 x 18.57 = 55.71 feet (approximately).
If you rounded 18.57 to 18.5, you would need 3 x 18.5 = 55.5 feet.
If you rounded 18.57 to 18.6, you would need 3 x 18.6 = 55.8 feet.
If you rounded 18.57 to 19, you would need 3 x 19 = 57 feet.
In each case, a decent approximation would be 60 feet.
