Question

5. The area of a trapezium is 0.95 m2 and its altitude is 19 cm. Find the sum of its parallel sides.
​

Answer 1

Answer:

Area of trapezium = 1/2(sum of parallel sides)*Height

Given,

Area = 0.95m²

altitude = 19cm = 0.19m

putting all values we get,

0.95 = 1/2(sum of parallel sides)(0.19)

sum of parallel sides = (0.95)*2/(0.19) = 10m (Ans)

Answer 2

The solution is provided below :

It is given that,

Area of the trapezium is = 0.95 m^2

And the altitude of the trapezium is given as = 19 cm = 0.19 m

To find : The sum of the parallel sides of the trapezium.

To calculate the sum of the sides of the trapezium that are parallel, we have to apply the formula of area if trapezium.

Area of the trapezium = 1/2 x (sum of parallel sides) x h

Let, y be the sum of the parallel sides.

Putting the values, we get,

$0.95 = \frac{1}{2} \times y \times 0.19$

$0.95 = \frac{0.19y}{2}$

$0.95 \times 2 = 0.19y$

$1.9 = 0.19y$

$\frac{1.9}{0.19} = y$

$y = 10 \: m$

So, the required answer is 10 m
