1. Answer:

   30m

   Step-by-step explanation:

   ar of trapezium = 1/2 ×(sum of parallel sides)×height

   450= 1/2×(18+12) ×h

   450 = 1/2 × 30 × h

   450 = 15 × h

   450/15 = h

   30 = h

   hence, the height of trapezium is 30m

2. Answer:

   Step-by-step explanation:

   Area of a trapezium : (sum of parallel sides/2)*height

   let other parallel sides be x

   so we get,

   450 = ({20+x}/2)*15

   450/18 ={20+x}/2

   (450*2) / 15=20+x

   (960/15)-20=x

   64-20=x

   44=x

   other parallel sides =44m
