The formula for the area of a triangle is A=1/2*h*b
Therefore:
(1/2)*4*5.5=11
The area of the sail is 11 feet squared

Area of a triangle: (1/2)bh, where b = base and h = height

(1/2) x 4 x (11/2)
= (4/2) x (11/2)
= 2 x (11/2)
= 11

1 is an odd number so let’s put 1 into n, (1)2+4 which equals 2+4 which is 6, 6 is not a prime number as it can has factors such as 2&3 not just 1&6.
