Mathematics Question on Area of a Polygon
The shape of the top surface of a table is a trapezium. Find its area if its parallel sides are 1 m and 1.2 m and perpendicular distance between them is 0.8 m.
Answer
Area of trapezium = 21 (Sum of parallel sides) × (Distances between parallel sides)
Area of top surface of the table = (21)×(a+b)h
= (21)×(1+1.2)0.8
= (21)×2.2×0.8 = 0.88
Area of top surface of the table is 0.88 m2 .
