Question

find the area of a trapezium whose parallel sides are 55cm and 47 CM and the distance between them is 20 cm​

Answer 1

the distance between parallel side of trapezium = height

1st side = 55cm

2nd side = 47cm

Area of trapezium =

1/2 × height × ( sum of parallel side )

= 1/2 × 20cm × (55 cm + 47cm)

= 1/2 × 20cm × 102cm

= 1/2 × 2040cm²

= 2040cm²/2

= 1020cm²

Answer 2

Answer:

Area of a trapezium is $1020\ cm^{2}$ .

Step-by-step explanation:

To find :  area of a trapezium .

Given : parallel sides of trapezium are $55$ cm and $47$ cm and the distance between them is $20$ cm​ .

Solution :

• As per given data we know that , parallel sides of trapezium are $55$ cm and $47$ cm and the distance between them is $20$ cm​ . We have to find it's area .
• Area of trapezium is given by following formula :

• Area of trapezium = $\frac{1}{2} \times ( sum \ of \ parallel \ sides )\times ( height )$

                                        $= \frac{1}{2} \times ( 55 + 47 )\times20 \\\\= \frac{1}{2} \times 102 \times 20 \\\\= 51 \times 20\\\\= 1020 \ cm ^{2}$
