It is: 3*1 = 3 inches
If a "1 inch triangle" means a triangle each of whose sides is 1 inch, then there is no answer to the question. These are equilateral triangles and equilateral triangles can tesselate to form a larger equilateral triangle. The fact that the large triangle is equilateral means that its three sides are equal so that its perimeter ie the sum of the three sides must be divisible by 3. 20 is not divisible by 3.

An equilateral 1 inch triangle is a plane figure and it does not have a cross-sectional area in any meaningful sense, just an area. Its area is 0.43 = sqrt(3)/4 square inches.

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.

No, an equilateral triangle can not be an obtuse triangle. All angles in an equilateral triangle are 60o. An obtuse triangle has 1 angle that is greater than 90o.
the ratio of the perimeter of triangle ABC to the perimeter of triangle JKL is 2:1. what is the perimeter of triangle JKL?
Area of a triangle = 1/2*base*height Use Pythagoras to find the height which is 7.794228634 inches Area = 1/2*9*7.794228634 = 35.07402885 square inches Answer: 35 square inches to the nearest square inch.
Yes. With the use of some deductive logic, in conjunction with careful and diligenteffort, you stand a good chance of succeeding at that task.Here is one indispensable piece of information that you'll require:An equilateral triangle is one in which the three sides are equal.Knowing that fact, and knowing the perimeter, and pondering undisturbed andundistracted for some period of time, it will eventually dawn on you that each sideof your equilateral triangle is precisely one-third ( 1/3 ) of the perimeter.
Six right angle triangles can be drawn inside an equilateral triangle
Let's express the side length of an equilateral triangle, a, in term of the height h.a = (1/3)(h)(sq.root of 3)The perimeter equals to 3a. So we have:3a = 3[(1/3)(h)(sq.root of 3)] = (h)(sq.root of 3)] = 18(sq.root of 3)
