Question

The area of a trapezium is 34 cm2 and its height is 4cm. One of the parallel sides of the trapezium is 10 cm, find the other parallel side.​

Answer 1

Answer:

Mensuration. The area of a trapezium is 34 cm2 and the length of one of the parallel sides is 10 cm and its height is 4 cm. Find the length of the other parallel side. Hence, the required other side = 7 cm.

Answer 2

Answer:

The other parallel side is $7cm$.

Step-by-step explanation:

We are given that area of trapezium is $34cm^{2}$.

The height of trapezium is $4cm$.

One of the parallel side is $10cm$.

We need to determine the other parallel side.

Let the other parallel side be $x$.

We know that

Area of trapezium is $\frac{1}{2} *height*sum of parallel sides$

$34=\frac{1}{2}*4*(10+x)$

$17=10+x$

$x=17-10$

$x=7cm$

Hence, the other parallel side is $7cm$.
