Hannah has a small square shaped garden with an area of 196 square feet. If she wants to put a fence around the garden, how many

A square is a quadrilateral that has the same length on every side.

The area of the garden is 196 square feet. To find the area of a garden, you have to multiply the length times the width. Since you know that both widths are the same, you can simply just calculate the square root of 196. The square root of 196 is 14. So you know that one side is 14 feet in length.

Now you will need to find the perimeter. The perimeter of any polygon is the lengths of all sides added up. Since there are 4 sides on a square, and each side is the same length, you can just add 14, 4 times. 14+14+14+14 equals 56. So the perimeter of the garden is 56 feet.

Hannah will need 56 feet of fencing.

Agata [3.3K]

Answer:

{ \tt{ \frac{56}{44.8}  =  \frac{35 }{(x + 4)} }} \\  \\ { \tt{56(x + 4) = 35 \times 44.8}} \\ \\  { \tt{56x + 224 = 1568}} \\  \\ { \tt{56x = 1344}} \\  \\ { \tt{x =  \frac{1344}{56} }} \\  \\ { \tt{x = 24}}

Idk how to explain my work :/ help ?
shtirl [24]

The total arc length around a circle is 360 degrees. So, these 3 arc with expressions given will all add up to 360.

(-2 + 8x) + (10x + 10) + (10x - 12) = 360

28x - 4 = 360

28x = 364

x = 13

Now that we know the value of x, we can plug that value into the expression for arc LM and solve for the measure.

LM = 10x - 12

LM = 10(13) - 12

LM = 118 degrees

Hope this helps! :)
