If one side of an equilateral hexagon has length 2x plus 1 what is the permiter?
A haxagon has 6 sides. An equilateral hexagon has 6 equal sides. So the perimeter is 6*(2x+1) = 12x+6
What is perimeter in maths?
The perimeter is the length plus width times 2.
Perimeter of rectangular?
Twice the (width plus length)
What can be concluded about a rectangles width if the ratio of length to perimeter is 1 to 3?
The width is half the length: The perimeter is twice the length plus twice the width. If the perimeter is 3 times the length, twice the width must be the length.
Explain how each angle in a equilateral triangle is 60 degrees?
Well, in an equilateral triangle, all three angles have to be equal. Plus, the sum of all the angles must be 180. Therefore, if you want to find on angle of an equilateral triangle, you would use the equation, 180/3=60
What is formula of finding the perimeter of a triangle?
Perimeter of a triangle = (length of the first side) plus (length of the second side) plus (length of the third side)
What is the formula for perimeter of a tiragle?
Perimeter of a triangle = (length of the first side) plus (length of the second side) plus (length of the third side)
The side length of an equilateral triangle is x plus 3 write an expression for the perimeter of a triangle?
In an equilateral triangle, all 3 sides are the same length, so your equation would look something like this: P=the perimeter of the triangle (x+3)=length of each side P=3(x+3) If you wanted to simplify further, you would distribute the 3 to both the x and the 3 inside of the parentheses, giving you P=3x+9.

The width is half the length: The perimeter is twice the length plus twice the width. If the perimeter is 3 times the length, twice the width must be the length.
How do you find the perimeter of an isosceles triangle when you only have one side and the base?
If you mean "isosceles" triangle, the perimeter is the sum of twice the known side plus the base.
Explain how each angle in a equilateral triangle is 60 degrees?
Well, in an equilateral triangle, all three angles have to be equal. Plus, the sum of all the angles must be 180. Therefore, if you want to find on angle of an equilateral triangle, you would use the equation, 180/3=60
How many degrees should there be in an isosceles triangle?
In the equilateral triangle, all the sides are the same length and all the angles are the same size (congruent). Since the sum of the angles of a triangle is always 180 degrees, we can figure out the measure of the angles of an equilateral triangle.Another Answer:-An isosceles triangle has 2 equal base angles plus another angle and the 3 interior angles add up to 180 degrees.
How do you work out the perimeter of a right-angled triangle?
The perimeter of a triangle is side A plus side B plus side C. Since we are talking about a right triangle, if you know two sides, then you know the third by the Pythagorean Theorem: A2 + B2 = C2
What is length plus width?
2 times length plus 2 times width = perimeterhalf the perimeter of a rectangle
