El área de un cuadrado se calcula como el producto de dos de sus lados. Si el área es de 1 600 cm2, ¿Cuáles son las dimensiones del cuadrado?

the lenght of the sides of the square is 40 m

Step-by-step explanation:

I will answer this in English, hope you can follow it or translate it.

This can be translated to:

"The area of a square is equal to the product of two of the sides.

If the area is 1600m^2, which are the dimensions of the square?"

First, the length of the 4 sides of a square is the same, let's write this as L.

Then the area of the square is L*L = L^2.

Then we have L^2 = 1600m^2

now we can apply the square root to both sides and get:

√(L^2) = L = √(1600m^2) = 40m

The length of all the sides of this square is 40m

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
