If an isosceles triangle is a triangle with 2 congruent equal sides if the third side is three times the length of the congruent sides and the perimeter is 75cm find the length of all three sides?
Let x be the length of one of the congruent sides, then the three sides are x, x, 3x. Perimeter = x + x + 3x = 5x = 75cm => x = 15cm Thus the three sides are 15cm, 15cm, 45cm.
What does write an expression for the perimeter mean?
Basically, the perimeter of a shape is the total legnth of all it's sides, therefore to write an expression for it, you need to get the legnths of the sides (even if there is a letter (eg: n)), then put them into an expression. For instance: A polygon has 2 sides that are 15cm long, 1 side that is 22cm long, 4 sides that are n long and 3 sides that are a long. To write the expression for the perimeter of this polygon as basically as possible, you would write: 15cm + 15cm + 22cm + n + n + n + n + a + a + a Now you need to simplify it: 52cm + 4n + 3a If you were asked this question, you would write 52cm + 4n + 3a as your answer. That is an expression for the perimeter of that particular polygon. If you apply the same theory to any question like the one you asked about, you would get it right.
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. 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.

What is the perimeter of 8cm and 15cm?
Perimeter is the total of all the sides. Let's assume your part-question relates to a rectangle. Four sides: 2 x 8cm and 2 x 15cm. I'm sure you can work it out from there...

Let x be the length of one of the congruent sides, then the three sides are x, x, 3x. Perimeter = x + x + 3x = 5x = 75cm => x = 15cm Thus the three sides are 15cm, 15cm, 45cm.
A regular hexagon has a side length of 15cm. What is the perimeter of the hexagon?
The perimeter of the hexagon is 6 times 15 = 90 cm
A regular polygon has?
A regular polygon is a polygon in which all the angles and sides are equal, say on a regular polygon if one side is 15cm if you know that they are all equal, all the other sides are 15cm, also you can assume on a regular polygon, that if one angle is 75o all the other angles are 75o

How many triangles have the perimeter of 15cm?
To determine the number of triangles with a perimeter of 15cm, we need to consider the possible side lengths that can form a triangle. The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. With a perimeter of 15cm, the possible side lengths could be (5cm, 5cm, 5cm) for an equilateral triangle, (6cm, 5cm, 4cm) for an isosceles triangle, or (7cm, 5cm, 3cm) for a scalene triangle. Therefore, there are 3 possible triangles that can have a perimeter of 15cm.
What is the perimeter of a square when the length of a side is 15Cm?
The perimeter of a square is any side times 4 since all 4 sides are equal. In this case it is 15 *4 cm or 60 cm.
