Answer:
2feets per year
Step-by-step explanation:
49,5-38,5=11feets --->this is how much it grew in 5,5years
11/5,5=2feets/year --->this is the yearly rate
X^3 / X^5 = X^ -2
you have to subtract the exponents when you’re dividing
you can just split the figure in 2 separate figures and them add the areas:
area rec. 1:
3m×3m= 9m²
area rec. 2:
3m× (2m+3m)
= 3m×5m
=15m²
total area:
9m²+15m²= 24m²
so here is the answer hope it helps
