a farmer is buying fencing to surround a square field of area 3600m^2. What length of fencing does he need to buy?
kirill115 [55]

Answer:

240 m

Step-by-step explanation:

The area of a square field is 3600 m².

We need to find the length of fencing he needs to buy. It means we need to find the perimeter of the field.

The area of a square field is given by :

A = side²

So,

s=\sqrt{3600} \ m\\\\s=60\ m

Length of fencing = perimeter

= 4(s)

= 4(60)

= 240 m

So, he would need to buy 240 m of fencing.

Dr. Ellison says that the equation y = 17x + 1 has a solution of (1,18).
nekit [7.7K]

The solution of an equation is the true value of the equation.

The true statement is <em>(a) Dr. Ellison is right</em>

<em />

The equation is given as:

\mathbf{y =17x + 1}

The solution is given as: (1,18)

Substitute 1 for x and 18 for y.

So, we have:

\mathbf{18 =17 \times 1 + 1}

Multiply

\mathbf{18 =17 + 1}

Add

\mathbf{18 =18}

The above equation is true.

Hence, the true statement is (a) Dr. Ellison is right
