  • Please prefer the picture for your answer.
  • We know, area of a ∆ = 1/2 × base × height.
  • Here, base = ( 7 + 1) units = 8 units.
  • Height = (7 - 1) units = 6 units.
  • Therefore, the area of the ∆
  • = (1/2 × 8 × 6) square units
  • = 24 square units.

<h3><em><u>Answer</u></em><em><u>:</u></em></h3>

<em><u>The </u></em><em><u>area </u></em><em><u>of </u></em><em><u>the </u></em><em><u>triangle</u></em><em><u> is</u></em><em><u> </u></em><em><u>2</u></em><em><u>4</u></em><em><u> </u></em><em><u>square</u></em><em><u> units</u></em><em><u>.</u></em>

Hope you could get an idea from it.

Hello!
When finding the perimeter of a rectangle, you have to consider the properties of a rectangle. A rectangle has two pairs of equal sides where one is the width, while the other one is the length. 
Now looking back at your question, it says "... a rectangle that is x units wide" ⇒ you let the width = x ; this is the same with "y units long" ⇒ length = y. Perimeter can just be : P = 24.  
Therefore,
The equation would be:
x + x + y + y = P. 
2x + 2y = P.
(Sub in P = 24)
∴ 2x + 2y = 24. (This should be your answer.)
:) Good luck (Message me if you have any problem)
