Given,

Perimeter = 15.7 inches

2a + b = 15.7

b = 15.7 - 2a

Hence, (15.7 - 2a) would be the length of the base.

Given Height of Dorsal Fin = 1/6 of Length of whale Sculpture,

and given length of whale sculpture = 1.5m or $1\frac{1}{2} m\\$

Height of Dorsal fin on scuplture = $(\frac{1}{6})(1\frac{1}{2} )\\$

= $(\frac{1}{6} )(\frac{3}{2}) \\= \frac{3}{12} \\= \frac{1}{4}m or 0.25m$
