Question

The parallel side of a Trapezium are 9 cm and 7 cm and its area is 80 CM square find its altitude​

Answer 1

The parallel side of a Trapezium are 9 cm and 7 cm and its area is 80 cm square then its altitude​ is 10 cm

Solution:

Given that parallel sides of trapezium = 9 cm and 7 cm

Area = 80 cm

The formula for area of trapezium is given as:

$\text { Area of a trapezium }=\frac{1}{2}(a+b) h$

where a and b are the sides of the trapezium, "h" is the height or altitude of the trapezium.

Here we have to find the altitude i.e. h

Thus  plugging in known values, we get

$\begin{array}{l}{80=\frac{1}{2}(9+7) h} \\\\ {80=8 h} \\\\ {h=\frac{80}{8}} \\\\ {h=10}\end{array}$

Thus the altitude of the trapezium is 10 cm
