The floor area of a square closet is 16 ft2. what is the length of one side of the closet? ft

The answer is 4ft

Step-by-step explanation:

The formula for calculating the area of a square is given as;

Area of a square = Length × Length

A = L²

Note that all the length of the sides of the square are equal.

Given the area of the square closet to be 16ft², to find the length of the closet, we will substitute the area given into the formula for calculating the area of square as given above to have;

16ft² = L²

L = √16ft²

L = ±4ft

Since the length of the square cannot be negative, therefore the length of one side of the square closet is 4ft.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
