Question

the area of trapezium is 180 m square and the distance between the two parallel sides is 12 if one of the parallel side is double The Other find the measure of The parallel sides answer

Answer 1

let one parallel side be x and other one be 2x
height=12m
area=1/2×h×(sum of parallel side)
180=1/2×12×(x+2x)
180/6=3x
30=3x
10=x
so one parallel side is 10 m and other is 20 m

Answer 2

let one side be x metre
=> other side =2x
area =180m sq.= 1/2(sum of parallel sides)height
=>1/2(x+2x)12=18=>6(3x)=180
=>18x=180
=>x=10
therefore one side =10 m
other side =10(2)=20m
hope you got it pls mark it as brainliest
