Answer:
the length of other parallel side of the trapezium is 48cm
MARK ME AS A BRAINLIST
As we know,
Area of trapezium = 1/2 X (Sum of parallel || sides) X height
Step-by-step explanation:
let length of side be 'x'
1/2 X (80 + x)cm X 4cm = 256 cm^2
80 + x = 256 X 2 ÷ 4
80 + x = 128
x = 128 – 80
x = 48
[therefore, length = 48 cm]
