Question

find the area of the trapezium whose parallel sides are 30cm and 20cm and the distance between them is 15cm​

Answer 1

Step-by-step explanation:

We know that

Area of trapezium = 1/2 × sum of parallel sides × height

= 1/2 × ( 30 + 20 ) × 15

= 1/2 × 50 × 15

= 25 × 15

= 375 cm^2

$\boxed {Area of trapezium = 375 Sq. cm}$

›»› The area of trapezium is 210 cm².

$\sf\green{\underline{\sf Given :}}$

The parallel sides of a trapezium is 20cm and 30cm long.

Distance between them is 15cm.

$\sf\orange{\underline{\sf To Find :}}$

The area of trapezium = ?

$\sf\blue{\underline{\sf Solution :}}$

As we know that

→ Area of trapezium = $\frac{1}{2}$ * (sum of parallel sides) * height.

→ Area of trapezium = $\frac{1}{2}$ * (a + b) * h

→ Area of trapezium = $\frac{1}{2}$* (20 + 30) * 15

→ Area of trapezium = $\frac{1}{2}$ * 50 * 15

→ Area of trapezium = 1 * 25 * 15

→ Area of trapezium = 25 * 15

→ Area of trapezium = 375

Hence, the area of a trapezium is 375 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.
