Answer:

The equilateral triangle sail has the greatest area.

Explanation:

The area of a triangle is defined by


A=(1)/(2) bh

Where
b is the base and
h is the height of the triangle.

Notice that we have a scalene triangle, an isosceles triangle and an equilateral triangle.

Scalene triangle area.


A_(scalene) =(1)/(2) (10)(4.9)=24.5ft^(2)

Isosceles triangle area.


A_(isosceles) =(1)/(2) (4)(9.8)=19.6 ft^(2)

Equilateral triangle area.


A_(equilateral) =(1)/(2) (8)(6.9)=27.6ft^(2)

Therefore, the equilateral triangle sail has the greatest area.
