Question

write formula of area- rhombus, trapezium​

Answer 1

area of rhombus=half * product of diagonals

area of trapezium

= half*distance b/w parallel sides*

sum of parallel sides

Answer 2

Answer:

Area of rhombus is $A=\frac{d_{1}+ d_{2}}{2}$  and trapezium is $A=\frac{a+ b}{2}\times h$

Step-by-step explanation:

Rhombus is a parallelogram with all sides and opposite angles are equal.

If $d_{1}$ and $d_{2}$ are the lengths of the diagonals, then the area of rhombus is

                                $A=\frac{d_{1}+ d_{2}}{2} sq. units$  

Trapezium is a quadrilateral with two sides parallel and the other two non parallel.

If $a$ and $b$ are the lengths of the parallel sides, and $h$ is the height between the parallel sides, then the area of trapezium is

                                $A=\frac{a+ b}{2}\times h sq. units$
