# 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=$$0.88m^2$$
