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.

How do you figure out if the area or perimeter needs to be squared?
the perimeter of a figure is never squared, but the area of a figure is always squared. Hope this helped :)
How do you calculate the perimeter and area of a square?
The perimeter of a square is four times the length of any side. The area is the length of a side multiplied by itself (which is to say, squared).
If the area is 900cm squared what is the perimeter?
The perimeter is 120 cm
How do you find the perimeter of a triangle if you know the area?
You cannot. For a given area, an equilateral triangle will have the smallest perimeter but that perimeter can be increased - without limit - without increasing the area.
What is the area and perimeter of a triangle if its dimensions are doubled?
Area is quadrupled (*4) and perimeter is doubled.
