Using trigonometry: height = 15.58845727 units and base = 9 units

Area = 1/2*15.58845727*9 = 70.148 square units to 3 d.p.

### What is the area of a right angle triangle when its perimeter is 18 cm?

It can have any area greater than 0 cm2 and less than or equal to 81(3-&radic;8) &asymp; 13.897 cm2. Without further information that provides the length of (at least) one side it is impossible to say which of these areas the triangle has. For example: base = 9 cm, hypotenuse = 9 cm &rArr; height = 18 - 9 - 9 cm = 0 cm &rArr; area = 9x0/2 = 0 cm2 This triangle does not actually exist and represents the minimum of the area. base = 6 cm, hypotenuse = 7.5 cm &rArr; height = 18 - 6 - 7.5 cm = 4.5 cm &rArr; area = 6x4.5/2 = 12.5 cm2 Note that base2 + height2 = 36 + 20.25 = 56.25 = 7.52 = hypotenuse2 and so this is a right angle triangle. base = 9(2-&radic;2) cm &asymp; 5.272 cm, hypotenuse = 18(&radic;2 -1) cm &asymp; 7.456 cm &rArr; height = 18 - 9(2-&radic;2) - 18(&radic;2 -1) cm = 9(2-&radic;2) cm &asymp; 5.272 cm &rArr; area = 9(2-&radic;2) x 9(2-&radic;2)/2 = 81(3-&radic;8) cm2 &asymp; 13.897 cm2 This triangle is a right angle triangle (check out Pythagoras on the lengths) and is the right angle triangle of largest area with perimeter 18 cm.
