The area of a square is 64cm squared. what is the perimeter of the square?

32cm

Step-by-step explanation:

Area of a square = side × side

Let one side be represented by (x)

Area of the square = (x)^2

; 64 = (x)^2

Hence...x = square root of (64)

; x = 8cm

Hence the perimeter of the square,

; 4 × (length of one side)

; 4 × 8cm

;Perimeter = 32 cm

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
