Answer 2

Given:

Two parallel sides of a trapezium=40m and 26m

Altitude=17m

To find:

The area of the trapezium

Solution:

The area of the trapezium is 561 $m^{2}$. (Option c)

We can find the area by following the given process-

We know that the area of a trapezium can be obtained by multiplying the sum of its parallel sides with its height and dividing by 2.

So, the area of a trapezium=1/2×sum of parallel sides×altitude

We are given that the altitude of the trapezium=17m

The sum of the parallel sides of the trapezium can be obtained by adding the two sides.

Using the values, we get

The sum of the parallel sides=(40+26)m

=66m

Now we will put the values in the formula to get the area of the trapezium.

The area of the trapezium=1/2×66×17

=33×17

=561 $m^{2}$

Therefore, the area of the trapezium is 561 $m^{2}$.
