Answer 2

Answer:

Sum of parallel sides of trapezium is $48\ cm$ .

Step-by-step explanation:

To find : sum of parallel sides of trapezium .

Given : area of a trapezium 2160 cm .Its height is 90cm .

Solution :  

• As per given data we know that ,area of a trapezium 2160 cm .Its height is 90cm .  
• Let , sum of parallel sides be $x$ .
• To find sum of parallel sides of trapezium we use following formula .
• Area of trapezium = $\frac{1}{2}\times( sum \ of \ parallel \ sides ) \times height$

        $2160 = \frac{1}{2}\times ( x ) \times 90 \\\\2160 = ( x )\times45 \\\\x = \frac{2160}{45} \\\\x = 48$
