Perimeter of a parallelogram land is 96m and it`s area is 270 square metres . If one of its side of the parallelogram is 18m. Find the length of the other side and also find the length of the altitude t and m.

lets assume side of parallelogram isa &b another twowill also be a&b) now its given that 2(a+b)=96 so a+b=48 ,one side is given 18 so another is 30 (48-18)
and area=base*height so there will be two height because 18&30 both can be choosen as base
in caseof 18 it will be 270/18=15m,and in case of 30 it will be 9m
