Answer:

h = 15.7 cm

Step-by-step explanation:

Area of trapezium = 1/2 * h (a + b)

220 = 1/2 * h (12 + 16)

220 = 1/2 * h * 28

220 = 14h

h = 220/14

h = 15.7

Hence altitude measures 15.7 cm

Hey Mate!!

Let the altitude be x.

Area of trapezium = 1/2 × (Sum of Parallel Sides) × Altitude

 =  > 220 =  \frac{1}{2}  \times (12 + 16)x \\  =  > 220 =  \frac{1}{2}  \times 28x \\  =  > 220 = 14x \\  =  > x = 220 \div 14 \\  =  > x = 15.71 \: cm \: (approx.)
