The lengths of the parallel sides of a trapezium are 9 cm and 12 cm….

The lengths of the parallel sides of a trapezium are 9 cm and 12 cm. lf the area of the trapezium is 105 cm2, find the perpendicular distance between the parallel sides.
  • A.
    5cm
  • B.
    7cm
  • C.
    10cm
  • D.
    15cm
Correct Answer: Option C
Explanation

(frac{1}{2}(a+b)times h = 105cm^2\
frac{1}{2}(9+12)times h = 105\
h = frac{105 times 2}{21} = 10cm)
