Answer 1

Answer:

area of trapezium = 1/2 × sum of lenght of parallel side × height

let the first parallel side be 1l and second parallel side be 2l.

substituting in formula

1200 =1/2 (1l + 2l ) × 125

1200 = 1/2 (3l ) × 125 ( dividing 125 by 2 )

1200 = 3l × 62.5

1200/62.5= 3l

19.2= 3l

3l= 19.2

l= 19.2/3

l=6.4

first || side = 1l = 6.4 × 1 = 6.4

second || side = 2l = 6.4 ×2 = 12.8 m

so lenght of side along canal is 12.8 m

sorry for talking rudely with you that day.
