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

Hope this answers the question.
Step-by-step explanation:
Factoring a number: If you use the number 10, for example, you have to find all the factors to factor it. 1, 2, 5, 10.
Factoring a trinomial: If you use the trinomial x^2 + 16 + 64, for example, to factor it you need to first find what numbers multiply up to 64 and also add up to 16. In this case, those numbers are 8, and so you get (x + 8)^2.
Answer:
x = 1/2
y = 4
Step-by-step explanation:
4x - y = -2 --------------------(I)
2x + 3y = 13 --------------------(II)
Multiply equation (I) by 3 and then add
(I)*3 12x - 3y = -6
(II) <u> 2x + 3y = 13 </u> {Now add and so y will be eliminated}
14x = 7
x = 7/14
x = 1/2
Plugin x = 1/2 in equation (I)
![4*\frac{1}{2}-y = -2](https://tex.z-dn.net/?f=4%2A%5Cfrac%7B1%7D%7B2%7D-y%20%3D%20-2)
2 - y = -2
-y = -2 - 2
-y = -4
y = 4

Answer:
7.14*10^-4rand
Step-by-step explanation:
If the cost of cereal is 35rand for 1 kg, this can be expressed as;
35 and = 1kg
To get the cost of 25grams, we can write
25g = x
0.025 kg = x
Divide both expressions
35/0.025 = 1/x
35x = 0.025
x = 0.025/35
x = 7.14*10^-4rand
Hence the cost of 25g is 7.14*10^-4rand
