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.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Suppose you know the perimeter and the height of an equilateral triangle explain how you would find the area of the triangle.?

The base is one third of the perimeter, half of the base times the height is the area.


How do you find the perimeter of a triangle when the perimeter is 177?

If you know the perimeter, there is no need to find it again.


How can you find the area if you know the perimeter?

Only if you also know the shape and proportions. An equilateral triangle, for example.


Can you find the height of a triangle when you know the perimeter?

No.


How can you use what you know about special triangle to find the perimeter?

The answer depends on what is special about the triangle and what else you know about it.


How do you find the area of a triangle when given 3 angles and the perimeter?

If you know the lengths of 2 sides and the included angle then use: Area of a triangle = 1/2*a*b*sinC


How do you find the perimeter of a triangle with sides like 2x and 5x and 6x?

To find the perimeter of a triangle you have to add up all the sides. So to find the perimeter of this triangle you just add 2x+5x+6x=13x. To find the actual perimeter you would have to know what x equals


Find the area of a triangle that has a perimeter of 21 inches?

I need to know more about the triangle, such as one or 2 of the angles, whether it is isosceles or equilateral, or whether the lengths share a certain ratio. For example, a triangle of sides 8,8 and 5 (perimeter of 21) will surely have a different area as compared to a triangle of sides 7,7 and 7 (perimeter of 21 as well)


How do you find the perimeter of a scalene triangle when you only know two sides and the area?

To get the perimeter, you need to add all three sides. I assume you can get the third side by inserting the numbers you know into Heron's formula.


How do you find the area if you know the perimeter?

It is impossible


How do you find the area of a equilateral triangle if you know the perimeter?

Divide the perimeter by 3 to find the length of each of its 3 equal sides Area = 0.5*side squared*sin(60 degrees) Alternatively use Pythagoras' theorem to find its height then area is: 0.5*base*height


Is it true that you can't find the perimeter if you don't know the area?

Not exactly. If I know the side lengths, I can still find the perimeter
