The cost of fertilizing a lawn is $0.25 per square foot. find the cost to fertilize the triangular lawn whose base is left parenthesis 8 plus startroot 19 endroot right parenthesis8+19 feet and altitude is startroot 76 endroot76 feet.

Let's convert the verbal descriptions into mathematical expressions to illustrate the problem more clearly. The base of the triangle is (8+√19) and the altitude or height is √76 . Then, the area of the triangle is

A=(1/2)(b)(h) = (1/2) (8+√19)(√76) = 19+8√19 square units

Then, you multiply this by $0.25 to determine the total cost. The answer would be $13.5.
