Question

area of trapezium whose two side are 5m, 50cm, and hight 50dm

Answer 1

It is the solution. Follow these steps given.

Answer 2

Solution -  

We know,  

Area of trapezium  

= 1/2 × (sum of || sides) × height  

One || side = 5m = 500cm  

Another || side = 50cm  

Height = 50dm = 500cm  

∴ Area of given trapezium  

= [ 1/2 × (500 + 50) × 500 ] cm²  

= [ 1/2 × 550 × 500 ] cm²  

= [ 275 × 500 ] cm²  

= 137,500 cm² Or 13.7500 m²  

Explaination -  

We know, a trapezium has 4 sides where 2 sides are parallel to each other and other 2 sides are may or may not be parallel to each other.  

But to find the area we also must know the distance between those parallel sides which can be said as height or altitude.  

So, to find the area, we have to move half multiplied by sum of parallel sides multiplied by distance between those parallel sides.  

[ ∴ 1/2 × sum of || sides × distance between || sides ]
