A = (4 * 6)/2
A = 12 square feet
A = 12 square feet
The formula to calculate the area of a triangle is:
Area = (base x height) / 2
In this case, the base of the sail is 4 feet, and the height is 6 feet. Plugging these values into the formula, we get:
Area = (4 x 6) / 2
Area = 24 / 2
Area = 12 square feet
Now, we know that one can of white paint covers 10 square feet. To determine how many cans of paint Aubrey needs, we divide the total area of the sail by the coverage of one can:
Number of cans = Total area / Coverage per can
Number of cans = 12 square feet / 10 square feet
Number of cans = 1.2 cans
Since we can't have a fraction of a can, Aubrey will need to round up to the nearest whole number.
Therefore, Aubrey will need 2 cans of white paint to paint the sail.
