m and 15 m. find the length of the non-parallel sides. (Round your answer to two decimal places)​

Answer 1

Answer:

ANSWER

21× (sum of 11 sides) ×height =168

∴336=(36+20)×height

∴height=56336=6m

∴ length of non parallel side =62+82

                                                 =100

∴ Answer                                =10cm
