Ineed as fast as possible. the diagram shows a trapezoidal flowerbed abcd in which ab is parallel to dc.
de and cf are perpendicular to ab. ab = 5m, bc = ad = 2m. dc = 3m and ae = fb. find the length of de and the area of the flowerbed.

The sum of these consecutive integers is equal to 9 less than 4 times the least of the integer. find the three integers
