two triangles with equal areas have their bases in the ratios 4:7.Findd the ratio of their heights.

yes  we can find area let's see
let area be constant k
area of triangle= 1/2*b*h
                         k=1/2*4x*h
                          h=k2/4x
similarly of another H=k2/7x                     (H is height of another triangle)
ratio=  H/h
       = k2/4x divide k2/7x
       = 7:4
