What is the perimeter of a triangle with one side 9cm if it has an area of 72cm squared?

Area = 1/2 (base x height) If the triangle is sitting on the 9cm side, then 72 = 1/2 ( 9 x height ) Height = 16 cm There are an infinite number of ways to draw the remaining two sides such that the height of the triangle is 16 cm. So the given information doesn't define a unique perimeter.


What is the area of a right triangle that is 4cm by 8cm?

The area of a right-angle triangle is half of the area of a rectangle 8cm x 4cm. Find the rectangle area and divide by half to find the area of the right-angle triangle. Therefore: 8 x 4 / 2 = 16cm2 * * * * * The above answer assumes that the two given lengths are the shorter legs of the triangle. It is, however, possible that these are the hypotenuse and one leg. In that case, the second leg is 4*sqrt(2) cm and the area of the triangle is 4 * 4*sqrt(2) / 2 = 8*sqrt(2) = 11.31 cm2.
