What is a triangle?
A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.
Given that the height of the cheese is 2.5 inches and the base is 4.75 inches.
The value of 1 inch is 2.54 centimeters.
Now convert 2.5 inches and 4.75 inches into centimeter:
2.5 inches = (2.5 × 2.54) centimeters = 6.35 centimeters
4.75 inches = (4.75 × 2.54) centimeters = 12.065 centimeters
The area of triangle is (1/2) × base × height
The area of the cheese is [(1/2) × 6.35 × 12.065] square centimeter
=38.31 square centimeter
= 38 square centimeters (nearest square centimeter)

Answer:
1 cookie = $1.25 1 cake = $15
Step-by-step explanation:
set up a system of equations:
let x = 1 cookie
let y = 1 cake
3x + 5y = 78.75
8x + 2y = 40
I multiplied the first equation by 2 to get: 6x + 10y = 157.50
I multiplied the second equation by -5 to get: -40x - 10y = -200.00
If you add both equations, the y-terms will be eliminated
-34x = -42.50
x = 1.25
Plug in 1.25 into equation to find value of y: 8(1.25) + 2y = 40
10 + 2y = 40
2y = 30
y = 15
