137.5 = x
He can run 137.5 ft
Given :
Two similar triangle.
To Find :
The ratio of the area of triangle abc to the area of triangle edc.
Solution :
ΔABC ~ ΔAPQ (AA criterion for similar triangles)
Since both the triangles are similar, using the theorem for areas of similar triangles we have :

Therefore, ratio of area of triangle is 1.4 .
