Answer:
68.8 cm²
Step-by-step explanation:
Area of trapezium = 1/2(sum of parallel sides) × height
Area = ½(8.6 + 12.9) × 6.4
Area = ½ × 21.5 × 6.4
Area = 21.5 × 3.2 = 68.8 cm²
86.8 cm^2
area of a trapezoid = 1/2h(b1+b2)
height = 6.4 cm
bases = 12.9 and 8.6
The bases are always the two sides that are parallel to each other.
A=1/2(6.4)(12.9+8.6)
