Question

Find the area of a trapezium whose parallel sides are 5 cm and 7 cm and height is 3 cm.​

Answer 1

Answer:18 cm^2

Step-by-step explanation:

We know that,

Area of trapezium= 1/2 ×(a+b)×h

Here a =5cm b=7cm c=3cm

So,

Area= 1/2 × (5+7) ×3

=1/2 × 12× 3

= 36/2

= 18

AREA OF TRAPEZIUM- 18cm^2

Answer 2

Answer:

The area of trapezium is  $18cm^2$

Step-by-step explanation:

Explanation:

Given in the question, Height of the trapezium = 3cm

Parallel sides of the trapezium = 5cm and 7cm.

Step 1:

Formula to find area of trapezium = $\frac{a + b}{2} h$

Where 'a' and 'b' are the parallel side of the trapezium and 'h' is the height of the trapezium.

Given, a = 5cm , b = 7 cm and h = 3cm on putting all these value in the formula we get,

Area of trapezium = $\frac{5+ 7}{2} .3$

⇒Area of trapezium = $\frac{12}{2}3$ = 6 × 3 = 18.

Final answer:

Hence, $18cm^2$ is the area of the trapezium.
