It is necessary to mention that the two triangles are similar.

Let the perimeter of the triangle MNP be x cm.

Since the triangles XYZ and MNP are similar triangles,

8/12 = x/80 (multiply both sides by 80)
640/12 = x
53.3333... = x
53 3/9 = x
53 1/3 = x

Thus, the perimeter of the triangle MNP is 53 1/3 cm.

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

How do you find the area of a triangle given only the perimeter?

It is possible depending on what type of triangle it is. For instance if it was an equilateral triangle then all sides would be equal and then by means of Pythagoras' theorem you could work out the height of the triangle and using the formula: 1/2*base*height = area


What is the ratio of the length of a side of an equilateral triangle to its perimeter?

Length of a side of an equilateral triangle : Perimeter = 1 : 3 For example, if the length of the sides of an equilateral triangle were 5cm each, then perimeter would be three times that much - 15cm. 5 : 15 is the same as 1 : 3 when simplified.
