If you have a rectangle with sides as follows: 4,4,3,3 the area is 12cm2 and the perimeter is 14. Area: 4cmx3cm=12cm2 Perimeter: * 4+4=8 * 3+3=6 * 8+6=14cm
The area of qa triangle is always half of the area of a rectangle with the same dimensions
Well, it helps immensely to know the formula for the area of a triangle. The area of a triangle is 1/2 (length of the base) times (height) .Knowing that, all you have to do is draw a triangle in such a way that the length of the base (in cm), multiplied by the height (in cm) is 12 . There are an infinite number of ways to do it, so finding one should not be a problem.

You can't without having incomplete units.
The area is 12cm2
No. The maximum are is attained when it is equilateral and that is less than 7 cm2
You don't have to do anything at all. As soon as you draw a triangle, it automaticallyhas area. The only trick for you is to figure out how much area it has.

Yes
A right-angle triangle is half of a square or rectangle. Draw a square or rectangle and draw a line from one corner to the corner diagonally opposite. You now have two triangles of the same area.

Because - if you draw lines at right-angles from the base of a triangle vertically until they reach the highest point, then draw a horizontal line that connects those points, touching the highest point of the triangle - the area outside the triangle (but inside the resulting quadrilateral) is exactly half the area of the quadrilateral.

Most people, when asked to draw a triangle, would probably draw an acute or maybe a right triangle.
