Question

4 Three vertices of a rectangle are (2, 9), (2, 2), and (7,2).• What are the coordinates of the fourth vertex?• What is the perimeter of the rectangle?anyHelp!

Answer 1

Given:

Part A:

To complete the rectangle, the coordinate of the fourth vertex will be (7,9).

Part B:

The length of the rectangle is 7 - 2 = 5 units

The with of the rectangle is 9 -2 2 = 7 units

Hence, the perimeter is gotten using the formula;

`\begin{gathered} P=2(l+w) \\ l=5 \\ w=7 \\ \\ P=2(5+7) \\ P=2(12) \\ P=2*12 \\ P=24units \end{gathered}`

Therefore, the perimeter of the rectangle is 24 nits.
