Find the sum of the lengths of the bases of a trapezium whose altitude is 11cm and whose area is `0. 55\ m^2dot`

Explanation

Given
area of trapizium `=0.55m^2` and
altitude of trapizium `=11cm`.
we know that ,
area of trapizium `=(1/2)xx`(sum of the bases )`xx`altitude
`implies 0.55=(1/2)xx`(sum of the bases )`xx(11/100) [:'1m =100cm]`
`implies` sum of the bases `= (0.55xx 2xx100)/11`
`implies` sum of bases `= (55xx2xx100)/(11xx100)`
`implies` sum of bases `= 10m`
Hence ,the sum of the length of the bases of a trapizium is `10m`.
