Solution:
The measure height of the large sail = 24 feet
The measure of base of the sail = 12 feet
We know that,
The sail of the sailboat is in the form of right angle triangle
The area of triangle is given as:
[tex]Area = \frac{1}{2} \times base \times height[/tex]
Substituting the values we get,
[tex]Area = \frac{1}{2} \times 12 \times 24\\\\Area = 6 \times 24\\\\Area = 144\ ft^2[/tex]
Thus the area of large sail is 144 square feet
