Question

the area of a trapezium is 36m^2 and the length of one of the parallel side is 10m and it's height is 4m.Find the length of the other parallel sides
​

Answer 1

Answer:

The other side (b) = 8m

Step-by-step explanation:

Given that,

Area = 36m²

1 parallel side = 10m

W. K. T.,

Area of a Trapezium = (a + b) / 2 * 4

=> 36m² = (10 + b) /2 *4

36 = (10 + b) * 2

36/2 = 10 + b

18 = 10 + b

18 - 10 = b

=> b = 8m

Answer 2

Answer:

Hey Friend,

Here is your answer.

If it helps so, Please mark me as the Brainliest.

Step-by-step explanation:

Area of a trapezium= 1/2 x h x (a+b)  

36$m^{2}$= $\frac{1}{2}$ x 4 x (10 + b)

You can cancel 2 and 4 with 2 as 1 and 4 as 2.

2 x (10+b).

2 x 10 + 2 x b.

20+ 2b.

b= $\frac{20}{2}$= 10cm

Hence the answer is 10 cm.
