Question

derivation of perimeter of an isosceles trapezium​

Answer 1

Answer:

P = a + b + 2c

The perimeter is the sum of the outer edge of the shape, so you just need to add the lengths of the sides. Because this is an isosceles trapezoid, the legs are the same length, so you can use 2c in the formula since both the legs are of equal length.
