Area of the trapezium is ,

where ,

a , b are parallel sides

h denotes height

________________________________

Area of the trapezium = 64 cm²

Height = 8 cm

Let one parallel side be x

Other =

Answer 2

Answer:

376

Step-by-step explanation:

64=1/2×(a+8)×1/3

64×2×3=1(a+8)

384=1a+8

1a=384-8

1a=376

a=376/1

a=376
