Question

A triangular sail has base of 4 feet and a height of 5 1/2 feet. What is the area of the sail?

Answer 1

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

Answer 2

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
