Step-by-step explanation:
Answer:
The polynomial of minimum degree is
.
Step-by-step explanation:
According to the statement, we appreciate that polynomial pass through the following points:
(i)
, (ii)
, (iii)
, (iv) 
From Algebra we know that any n-th grade polynomial can be constructed by knowing n+1 different points. Hence, the polynomial of minimum degree is a quartic function. The polynomial has the following form:

We proceed to expand the expression until standard form is obtained:




If we know that
, then:



Then, the polynomial is:



The polynomial of minimum degree is
.
Answer:7,560cm
Step-by-step explanation: Area is found by multiplying each side by each other. 7 x 6 x 12 x 15=7560
7 x 6=42
12 x 15=180
180 x 42=7560
