Area of trapezium = 1/2 × (sum of all parallel sides) × h
21.62 = 1/2 × (3.8+5.4) × h
43.24 = 9.2h
h = 43.24/9.2
h = 4.7 cm
21.62 = 1/2 × (3.8+5.4) × h
43.24 = 9.2h
h = 43.24/9.2
h = 4.7 cm
but 1/2×(3.8+5.4) so ans is 4.6
how 43.24 is coming
2 in the denominator goes in the right side since it is in division it will multiply with the number present there , thats why 21.62 × 2 = 43.24
ok
