Question

the area of trapezium of height 3m is 12m². if one of the parallel sides is 2m more than the other, find the lengths of trapezium.​

Answer 1

Step-by-step explanation:

We know the identify, Area of trapezium

$\text{\( =\dfrac{1}{2} \times \) (sum of parallel sides) \( \times \) altihide}$

According to question, let two parallel sides of trapezium are x cm and (x+2) cm .

$\[ \begin{array}{l} \displaystyle \rm \therefore 12=\frac{1}{2} \times[x+(x+2)] \times 3 \\ \\ \rm 8=2 x+2 \\ \\ \rm 2 x=6 \\ \\ \boxed{\red { \rm x=3}} \end{array} \]$

Length of parallel sides of trapezium are 3 cm and 5 cm.
