<PRE><B>Question 949509</B>
c=leech=25 ft; a=height=24 ft; b=base
{{{b^2=c^2-a^2}}}
{{{b^2=(26^2)ft^2-(24^2)ft^2}}} 
{{{b^2=(676)ft^2-(576)ft^2}}} 
{{{b^2=(100)ft^2}}} find square root of each side.
{{{b=sqrt(100ft^2)}}}
b=10 ft Base is 10 feet.
Area=1/2ba=1/2(10 feet)(24 feet)=120 sq ft  The area of the sail is 120 sq ft.
120 sq ft($10/sq ft)=$1200 ANSWER: The cost of the sail is $1200.
