Question

Top surface of a table is trapezium in shape. Find its area if its parallel sides are $1m$ and $1.2m$ and perpendicular distance between them is $0.8m$.

Answer 1

The given figure is:

Lengths of the parallel sides are $1.2m$ and $1m$ and the perpendicular distance between them is $0.8m$.
Therefore, area of the trapezium shaped surface$=\frac{1}{2}\times$(Sum of the parallel sides)$\times$(Perpendicular distance)
$=\frac{1}{2}\times (1.2+1)\times \left(0.8\right)$
$=\frac{1}{2}\times 2.2\times 0.8$
$=1.1\times 0.8$
$=0.88m^2$
Therefore, the surface area of table is $=0.88m^2$
