Given,
Area of Trapezium => 1/2(a+b)h = 480cm²
Height (h) = 15cms
Length of one parallel side (a) => 20cms
Required to find: Second parallel side (b)
=> 1/2(a+b)h = 480cm²
=> 1/2(20+b)×15 = 480cm²
=> 20+b = 480×2/15
=> 20+b = 960/15
=> b = 64-20
=> b = 44cms.
Length of second parallel side => b = 44cms.
