Q2. If the area of trapezium is 42 m2 and two parallel
sides are 6m and 80dm respectively find the altitude.
a. 7m
b.8m
c. 6m​

Answer 1

Step-by-step explanation:

Area of trapezium =

$\frac{1}{2} \times (sum \: of \: parallel \: sides) \times height$

So sum of parallel sides are= 6m +8m =14m

Area = 42 m2

$42 = \frac{1}{2} \times 14 \times height \\ \\ \\ 42 = 7 \times height \\ height = \frac{42}{7} \\ \\ height = 6$
