Answer:
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)
