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.

In Little League, the bases are squares with sides of 14 inches. The expression \(\sqrt{(\text{s}^{2} + \text{s}^{2})}\) represents the distance diagonally across a square of side length s. Estimate the diagonal distance across a base to the nearest inch.

The formula \(\text{t} = \cfrac{\sqrt{\text{h}}}{4}\) represents the time t in seconds that it takes an object to fall from a height of h feet. If a rock falls from a height of 125 feet, estimate how long it will take to reach the ground.
