Find the altitude of a trapezium, the sum of the length of whose bases is 6.5cm and whose area is `26 c m^2dot`

Explanation

Given
Sum of the length of bases `=6.5cm` and
area of trapizium `=26cm^2`
we know
area of trapizium `=(1/2)xx` (sum of length of bases )`xx` altitude
` implies 26=(1/2)xx6.5xx`altitude
`implies` altitude `=(26xx2)/6.5=8cm`.
hence we get required result.
