Kerala Board Solutions for Chapter: Area of Quadrilaterals, Exercise 4: Exercise 4

The lengths of the parallel sides of a trapezium are $30 \mathrm{centimetres}$, $10 \mathrm{centimetres}$ and the distance between them is $20 \mathrm{centimetres}$. The area is $\mathrm{K} {\mathrm{cm}}^2$. Find the value for $\mathrm{K}$.

Compute the area of the trapezium shown below:

(Express the result in $\mathrm{sq}.\mathrm{cm}$).

Compute the area of the hexagon below.

(Express the result in ${\mathrm{cm}}^2$)

This is a picture drawn in the lesson construction of quadrilaterals.

What is the area of the large trapezium made up of the given four smaller trapeziums?
(Express the result in ${\mathrm{cm}}^2$)
