Answer:
A = 24 m²
Step-by-step explanation:
Hello!
This question is very easy if you know the formulas to find the area of any shape!
Since this is a rectangle, we use the formula to find the area of a rectangle which is:
Where as:
l = length
w = wide
In our case we have:
l = 2
w = 12
We multiply that together according to the formula:
2 × 12 = 24
Thus, making the answer as 24m²
Hope this helps you!

Answer:
Step-by-step explanation:
We want to find the equation of a circle with a center at (7, 2) and a point on the circle at (2, 5).
First, recall that the equation of a circle is given by:
Where (<em>h, k</em>) is the center and <em>r</em> is the radius.
Since our center is at (7, 2), <em>h</em> = 7 and <em>k</em> = 2. Substitute:
Next, the since a point on the circle is (2, 5), <em>y</em> = 5 when <em>x</em> = 2. Substitute:
Solve for <em>r: </em>

Simplify. Thus:
Finally, add:
We don't need to take the square root of both sides, as we will have the square it again anyways.
Therefore, our equation is:
