What is the area of a 14 centimeter long and 10 centimeters wide in square meters

0.014 m^2

Step-by-step explanation:

Since the figure has a length and width, I assume it's a rectangle.

area = length * width

area = 14 cm * 10 cm

area = 140 cm^2

Now we convert to square meters.

area = 140 cm^2 * (1 m)/(100 cm) * (1 m)/(100 cm) = 0.014 m^2

0.014 m^2

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

it is 570
