Question

nadia wants to enclose a square garden with fencing has an area of 141 ft.² to the nearest foot how much fencing will she need explain

Answer 1

We know that area of the square is 141 square feet. Therefore, we can figure out the dimension of square using formula for area as shown below:

$Area=a^{2}\\141=a^{2}\\a=\sqrt{141}=11.874$

We know that fencing is used along the sides of the square. Therefore, amount of fencing required will be equal to perimeter of square.

Hence, we can write:

$\text{Amount of fencing}=\text{Perimeter of square}$

$\text{Amount of fencing}=4a=4(11.874)=47.496$

Upon rounding to nearest foot, we get the amount of fencing required as 48 feet.
