The area of a trapezium is 480 sq cm, the distance between two parallel sides is 15 cm and one of the parallel side is 20 cm. The other parallel side is:
Answer & explanation
Correct answer: option 3
Area of trapezium = ½ h (a+b)
480 = ½ (15) (20+b)
20+b = (480 x 2)/15
20+b=64
b=44cm
480 = ½ (15) (20+b)
20+b = (480 x 2)/15
20+b=64
b=44cm
