1.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 top trapezium surface of the table=(\frac{1}2\times (sum\; of \;parallel \;sides)\times (distances \;between\; them)\)

\(=\frac{1}2\times(1+1.2)\times0.8 m^2\)

\(=\frac{1}2\times 2.2 \times 0.8 m^2\)

\(=(1.1\times 0.8)=0.88m^2\)

So, the area of top trapezium surface of the table=\(0.88m^2\)
