Question

The area of a trapezium shaped field is 450m2
. Find the height of the field if the
length of the parallel sides are 18m and 12m.

Answer 1

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

Answer 2

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
