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