Find the area of a trapezium whose parallel sides are 25 cm and 13 cm and non-parallel sides are 10 cm each.
A152 sq. cm
B114 sq. cm
C144 sq. cm
D190 sq. cm
✓ Correct Answer: A — 152 sq. cm
Drop perpendiculars to form a rectangle and two triangles. Base of each triangle = (25-13)/2 = 6. Height = sqrt(10^2 - 6^2) = 8. Area = 0.5 * (25+13) * 8 = 152.
