Question

1. nadia wants to enclose a square garden with fencing. it has an area of 141 square feet. to the nearest foot, how much fencing will she need? explain.

1-4 evaluate square roots and cube roots 7

Explanation:

Step1: Find side - length of square

The area formula for a square is $A = s^{2}$, where $A$ is the area and $s$ is the side - length. Given $A = 141$ square feet, then $s=\sqrt{141}$.

Step2: Calculate the perimeter of the square

The perimeter formula for a square is $P = 4s$. Substituting $s=\sqrt{141}$ into the perimeter formula, we get $P = 4\sqrt{141}$. Now, $\sqrt{141}\approx11.87$, and $P = 4\times11.87 = 47.48\approx47$ feet.

Answer:

47 feet
