Answer: Total area 2800 sq.yards
Step-by-step explanation:
First roof
2 rectangles and 2 trangles
for rectangles area = b*h
then area of one rectangle = 20*30 = 600 sq.yards
We have 2 rectangles then 2 * 600 = 1200 s. yards
for triangles area 1/2 b*h
Then area of one triangle = 0.5* 5*20 = 50 sq.yards
We have 2 triangles then 2 * 50 = 100 sq.yards : 1300 sq.yards
Total area first roof = 1300 sq.yards
Second roof
Area of rectangle = b*h = 25*60 = 1500sq.yards
Total area second roof = 1500 sq.yards

Answer:
P(t) = 10t - 400
Step-by-step explanation:
Selling price of each ticket = $10
Cost of setting up the dance= $400
Profit = Revenue - cost
Revenue = price × quantity
Revenue that will maximize profit = 10t
where t= quantity of tickets that maximises profits
Cost = $400
Profit(t) = Revenue - cost
P(t)= 10t - 400
