Trapezoid:

Trapezoid is a type of quadrilateral having one set of parallel sides and other sets of non-parallel sides.
 

Trapezoid


Where, ‘a’ and ‘b’ are parallel sides and ‘c’ and ‘d’ are non-parallel sides and ‘h’ is its height.

 

Trapezoid Frequently Asked Questions:

Question 1: How to find the area of a trapezoid?

The area of a trapezoid is computed by multiplying the average of the parallel sides by the height of the trapezoid.


A = 1/2 x (a + b) x height


Trapezoid 1


Example:


Calculate the area of a trapezoid whose height is 15cm and length of parallel sides are 8cm and 18cm?


Area of trapezoid,


A = 1/2 x (a + b) x height


height,h=15cm


Parallel sides= 8cm and 18cm


So, Area of trapezoid = (1/2 )*15*(8+18) sq.cm


                                  = 195 sq.cm

 

Question 2: What is a trapezoid?

Trapezoid is a type of quadrilateral having one set of parallel sides and other sets of non-parallel sides.
 

Trapezoid 2


Where, ‘a’ and ‘b’ are parallel sides and ‘c’ and ‘d’ are non-parallel sides and ‘h’ is its height.

There are three type of trapezoid:
 

  • Isosceles Trapezoid: one in which the legs or non-parallel sides of the trapezoid are of equal length.
  • Scalene Trapezoid: one in which neither the sides nor the angles of the trapezoid are equal.
  • Right Trapezoid: one that has two right angles.
