Question

the area of trapezium is 787 square and perpendicular distance between parallel side is 13 cm find the length of other parallel side if one of them is 54 cm long​

Answer 1

Given:-

The Area of trapezium =787cm²

Height =13cm

One of parallel side=54c

let the other parallel side be x

ATQ

Area of trapezium=1/2 × (sum of parallel side) × h 787=1/2 × (x+54)×13

==>(x+54)13=787×2

==>13x+702=1574

==>13x=1574-702

==>13x=872

==>x=67 (approx)
