Question

if the area of isosceles trapezium whose parallel sides are 38.7 and 22.3 cm is 183 root 2 then find its other two non parallel sides are

please answer this question

​

Answer 1

Answer:

the answer is 11.8

Step-by-step explanation:

Hey fellow humans of this dreadful earth. Whoever is it who posted the answer first pls remove it as it is wrong. U got me confused for a really long time.

area of trapezium =1/2*(sum of parallel sides)*height

183√2=1/2*(38.7+22.3)*h

h=183√2*2/61

h=6√2(ae=h)

if abcd is trapezium and e and f are perpendicular  then de= 38.7-22.3/2=8.2

ad=√ae^2+de^2=√6√2^2+8.2^2=11.8

For better understanding draw a diagram(sorry that I couldn't upload one)
