Can someone show me the steps on how i got 100ft

Check the picture below.

so we have two rectangles and one triangle, as you see there.

now, the large rectangle is just a 10x8, so that's 80 ft².

the small rectangle is just a 4x4, so that's 16 ft².

the small triangle, notice, it has a right-angle, thus it has a height of 4, and a base of 2.

recall A = (1/2)bh, so the area of the triangle is (1/2)(2)(4) = 4 ft².

80 + 16 + 4 = 100 ft².

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
