Question

22. In the Fig. 15.34, the outer trapezium ABCD
has area 320 cm2. The area of the shade
region is 140cm2. Find the area of the in
trapezium EFGH. If the lengths of the paral
sides of the inner trapezium are 16 cm and
20 cm, find height HI.​

Answer 1

Answer:height =10

Step-by-step explanation:

Answer 2

Answer:

Here's you answer

Step-by-step explanation:

Given area of outer trap. is 320cm2

Shaded region = 140cm2

Area of inner trap. = outer - shaded

Now, area of inner trap. = 320- 140 = 180cm2

lengths of parallels = 16cm , 20cm

$\frac{1}{2} \times sum \: of \: || sides \: \times h \\ = 180$

Now,

1/2 x 36 x h = 180cm

H = 10cm
