Question

the area of the trapezium whose height is 14cm and theparallel sides are 18cm and 9cm is*​

Answer 1

Answer:

hello dear,

Step-by-step explanation:

To calculate the area of a trapezium, divide it into a rectangle and two triangles as shown below. Now, piece together the triangular ends so that the trapezium is divided into a triangle and rectangle. The base of the triangle is the difference between the lengths of two parallel sides. That is, a – b.

Answer 2

Answer :

Area of the trapezium is 189 cm ².

Explanation:

• Given :Height of trapezium = 14 cm

1. One parallel sides of trapezium =18cm
2. Second parallel sides of trapezium = 9 cm

• Find : The area of the trapezium

Solution:

The parallel sides are 18cm and 9cm

By using the formula

The area of trapezium =

= 1 / 2 × ( sum of parallel sides ) × height

= 1 / 2 × ( 18 + 9 ) × 14

= 1 / 2 × 27 × 14

= 1 × 27 × 7

= 1 × 189

= 189 cm²

Therefore, the area of the trapezium is 189 cm ²
