Answer:
16 cm and 6 cm
Step-by-step explanation:
Trapezium area = 121 cm^2.
Distance between parallel sides = 11 cm
Sum of parallel sides = (121 * 2)/11
=> 22 cm
One parallel side is 10 cm shorter than the second.
Let the longer side = x and shorter side = x - 10
=> x + x - 10 = 22
=> 2x - 10 = 22
=> 2x = 32
=> 16 cm
Hence,
Longer side = 16 cm and shorter side = 6 cm
