Answer» Answer: 13.6 cm Step-by-step explanation: AREA of TRAPEZOID = 1/2 (sum of parallel sides) × h 144.5 × 2 = (20.4 + 2ND side)× 8.5 289÷8.5 = 20.4 + 2nd side 34-20.4 = 2nd side 2nd side = 13.6

Answer:

13.6 cm

Step-by-step explanation:

AREA of TRAPEZOID = 1/2 (sum of parallel sides) × h

144.5 × 2 = (20.4 + 2ND side)× 8.5

289÷8.5 = 20.4 + 2nd side

34-20.4 = 2nd side

2nd side = 13.6
