Question

Find the area of a trapezium whose parallel side are 24cm 20cm and the distance between them is 15cm

Answer 1

Answer:

Step-by-step explanation:

• Area of trapezium = 1/2 x (sum of parallel sides ) x height

                                       = 1/2 x ( 24 + 20 ) x 15

                                       = 44/2 x 15 = 330 cm².

›»› The area of trapezium is 210 cm².

Given :

The parallel sides of a trapezium is 20 cm and 18 cm long.

Distance between them is 15 cm.

To Find :

The area of trapezium = ?

Solution :

As we know that

→ Area of trapezium = 1/2 * (sum of parallel sides) * height.

→ Area of trapezium = 1/2 * (a + b) * h

→ Area of trapezium = 1/2 * (20 + 18) * 15

→ Area of trapezium = 1/2 * 28 * 15

→ Area of trapezium = 1 * 14 * 15

→ Area of trapezium = 14 * 15

→ Area of trapezium = 210

Hence, the area of a trapezium is 210 cm².

Extra Brainly Knowledge :

❒ A trapezium is also a quadrilateral, which is defined shape with four unequal sides and two non-parallel sides.

❒ There are some more examples of trapezium or quadrilateral.

Rectangle.

Square.

Rhombus.

Parallelogram.

❒ The sum of all four angles of a trapezium or a quadrilateral is 360°. This statement is call angle sum property of a trapezium or a quadrilateral.

Formula of trapezium :

Area = 1/2 * (sum of parallel sides) * height.

Perimeter = Sum of all sides.
