The drawing shows an isosceles trapezoid.
What is its perimeter?
To find the perimeter of the isosceles trapezoid, consider the following steps:
Therefore, the perimeter of the isosceles trapezoid is .

Calculate the perimeter of the trapezoid according to the following data:
An isosceles trapezoid has two parallel bases (top and bottom) and two equal slanted sides. In this problem, both slanted sides are 5 units long.
Look at the diagram carefully! The two slanted sides (legs) are both labeled with the same number. Here, both diagonal sides show 5, so they're equal.
No! For perimeter, you simply add up all the side lengths. Special formulas are only needed for area calculations.
In an isosceles trapezoid, if you know three sides, you can find the fourth! The two legs are always equal, so if one leg is given, the other leg has the same length.
Yes! As long as you know it's an isosceles trapezoid with sides 3, 5, and 7, you know the pattern: one base is 3, both legs are 5, and the other base is 7.
