and surely you know how much that is.
Because they all have a different x number. Even though the y numbers are the same you can tell wether a set of numbers are a function by the x numbers. So since there are different x numbers it is a function. I hope this helps!
Answer:
30 cm^2 approximately
Step-by-step explanation:
The formula for calculating the area of a octagon is 2 (1 + √2) x^2 (x : side length)
2 + 2√2 × 100 = 30 cm^2 approximately
The middle is a square with side length of 12cm
Area of the square = 12 x 12 = 144 cm^2
There are 4 triangles with base of 13cm and height of 8 cm
Area of triangle = 1/2 x base x height
Area = 1/2 x 12 x 8 = 48cm^2 each
48 x 4 = 192 cm^2
Total area = 144 + 192 = 336 cm^2
