A university is trying to determine what price to charge for tickets to football games. At a price of $21 per ticket, attendance averages 40,000 people per game. Every decrease of $3 adds 10,000 people to the average
number. Every person at the game spends an average of $3.00 on concessions. What price per ticket should be
charged in order to maximize revenue? How many people will attend at that price?

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

parallelogram is the   answer

well, if it's triangular garden, the triangle could represent the garden.
