Question

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 1

Area of trapezium = $\frac{1}{2}$ (Sum of parallel sides) $\times$ (Distances between parallel sides)
Area of top surface of the table = ($\frac{1}{2}$)$\times$(a+b)h
= ($\frac{1}{2}$)$\times$(1+1.2)0.8
= ($\frac{1}{2}$)$\times$2.2$\times$0.8 = 0.88
Area of top surface of the table is 0.88 m2 .
