Question

a field is in the from of a trpezium .its area is 1586 m2 and the distance between its parallel sides is 26m. if one of the parellel sides is 84m .find the other

Answer 1

let the length of other parallel side be x m
distant between parallel sides 26m
area of trapezium= 1/2×sum of parallel sides x distance between parallel sides
1586= 1/2(84+x)×26
1586×2÷26= 122
x= 122-84= 38
