Perimeter of Isosceles Trapezium

The perimeter of an isosceles trapezium is the total length of its four sides. By adding the length of all four sides, we get the perimeter of the shape. The formula for the perimeter of an isosceles trapezium is 𝑃 = 𝑎 + 𝑏 + 2𝑐, where a and b are the parallel sides, and c is the length of the non-parallel sides (equal). For instance, if an isosceles trapezium has parallel sides a = 6, b = 8, and non-parallel sides c = 5, then its perimeter is P = 6 + 8 + 2(5) = 24.

Let’s consider another example of an isosceles trapezium with parallel side lengths 𝑎 = 10, 𝑏 = 14, and non-parallel sides 𝑐 = 7. So the perimeter of the trapezium will be: 𝑃 = 𝑎 + 𝑏 + 2𝑐 = 10 + 14 + 2(7) = 38.

To find the perimeter of an isosceles trapezium, we just need to apply the given formula and sum all the sides of the trapezium. For instance, a given trapezium has the sides of a = 8, b = 12, and c = 6. Perimeter = sum of all sides = 8 + 12 + 2(6) = 32 cm. Example Problem on Perimeter of Isosceles Trapezium - For finding the perimeter of an isosceles trapezium, we use the formula, 𝑃 = 𝑎 + 𝑏 + 2𝑐. For example, let’s say, a = 9 cm, b = 5 cm, and c = 3 cm. Now, the perimeter = sum of all sides = 9 + 5 + 2(3) = 20 cm. Therefore, the perimeter of the isosceles trapezium is 20 cm.

Learning some tips and tricks makes it easier for children to calculate the perimeter of isosceles trapeziums. Here are some tips and tricks given below: Always remember that an isosceles trapezium’s perimeter is simply the sum of the four sides of the shape. For that, use the formula, 𝑃 = 𝑎 + 𝑏 + 2𝑐. Calculating the perimeter of an isosceles trapezium starts by determining the length of each side, ensuring the pair of non-parallel sides are equal. To reduce confusion, specifically arrange the indicated side lengths if you need the perimeter of a group of trapeziums. After that, apply the formula to each trapezium. To avoid mistakes when adding the perimeter, make sure the side lengths are precise and constant for common uses like gardening and architecture. If you are given the semi-perimeter, which is half the perimeter, you can multiply it by 2 to determine the full perimeter. Area-related calculations often use the semi-perimeter, although not directly for trapeziums.

Perimeter: The total length of the sides of a shape. Isosceles Trapezium: A quadrilateral with one pair of parallel sides and the other pair of sides equal in length. Parallel Sides: The two sides of the trapezium that are parallel to each other. Non-parallel Sides: The two sides of the trapezium that are not parallel but are equal in length in an isosceles trapezium. Formula of Perimeter: The mathematical expression used to calculate the perimeter of an isosceles trapezium is 𝑃 = 𝑎 + 𝑏 + 2𝑐.
