Answer:
58,187.5 m²
Step-by-step explanation:
1 cm : 25 m 
7 cm = 25 × 7 m 
7 × 25 = 175 m 
13.3 × 25 = 332.5 m
area = 332.5 m × 175 m

Answer:
f(x) = 8 - 1.5x
Step-by-step explanation:
Here, we want to write a function that can be used to describe the x th term of the sequence 
Mathematically, this can be calculated by looking at the numbers in the sequence 
The difference between each successive term
is -1.5 ( 6.5-8, 3.5 -5)
So the formula for then x th term will be;
f(x) = 8 - 1.5x
where x refers to the number of the term , for example the 4th term
