Super easy will give brainleist if done before 10 pm pls hurry. if u have time pls me on other questions you < 3

Step-by-step explanation:

10. We know the area of a rectangle is

A=L*W

They gave us the area so we can plug it in

30 = L*W

Since we know two points, we know one side of the rectangle is the distance between the two points.  So one side is 7-2 = 5.  We can plug that into the formula.

30 = 5W

W = 6 (divide both sides by 5)

So now we know the width of the rectangle is 6.  That means the other coordinates are (6,2) and (6,7).  

11. To find the perimeter of a rectangle, we would need to find the length and the width of the triangle.  So we would need to subtract one x value from another x value and multiply that by 2.  Then subtract one y value from the other y value and multiply that by 2.  Add  both of those values to get the perimeter.

Equation:

P = 2 * (Change in X) + 2 * (Change in Y)

idk i would have to be there to under stand it

step-by-step explanation:

idk i would have to be there to under stand it

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
