You want to wire a square piece of land that has an area of 196 square meters. How many meters of wire is needed to fence the land by giving it 5 turns with the wire

Step-by-step explanatio

We look for the side

To know how many meters of wire we must first know the measurement of the sides of the land. They give us a land area of 196 m², as the land is square, we can take the square root of the area and we have the dimension of the sides

L = √196 m²

L = 14 m

Once the value of the side of the land is obtained, we proceed to determine the perimeter of the land, which will give us the size of the wire to fence

P = L + L + L + L

P = 14m + 14m + 14m + 14m

P = 56 m (this is the dimension of the wire for one turn of the ground)

They ask us for 5 laps.

56m * 5 = 280m

it takes 280 m

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

stops on an even number.
