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

c is the correct answer

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
