the area of the sail us 1/2(the area of a rectangle with the two sides from above) so . . .Originally Posted by leleirvin
1/2((4x)(3x+10))

6x^2 +20x square feet
Suppose you have a sailboat with one triangular sail. The base of the sail is 4x feet and it's height is 3x + 10 feet. Write a binomial that in terms of x for the area of the sail. Hint: The area of a triangle is 1/2 of the area of a rectangle.
