In words:
[ height of elephant ] / [ shadow of elephant ] =
[ height of telephone booth ] / [ shadow of telephone booth ]
---------------------------------------------------------
Let +x+ = the height of the telephone booth in feet
+9.1+%2F+31.9+=+x+%2F+29.4+
Multiply both sides by +31.9%2A29.4+
+9.1%2A29.4+=+31.9x+
+267.54+=+31.9x+
+x+=+8.3868+ ft
