Step-by-step explanation:

Correct Question

how to find area of Trapezium when parallel sides are 20 and 25 m and non parallel sides are 14 m and13 m​.

Answer:

We know that

area of trapezium = 1/2* sum of parallel sides* distance b/w them.

So, we have sum of parallel sides as 20+25 = 45m.

But the distance is unknown.

To find the distance ,

We will draw a line depicting the height at 90 degree.

Now in this, we will apply pythagoras theorem-

$x^{2} + 5^{2} = 13^{2}$   ________________ Subtraction of 25 and 20

Solving this we get x = 12m i.e the height.

Now, we can add it in formula as

1/2*45*12

= 270 metre square

HENCE SOLVED!!!

NOTE:

It cannot be rhombus as the sides of rhombus are always equal.
