Question

the area of a rectangle is 75 square centimeters the rectangle is 5 centimeters wide how long is the rectangle​

Answer 1

Answer:

15 centimeters.

Step-by-step explanation:

To find the area of a rectangle, you have to multiply the length by the width.

In this case, the width is 5 centimeters.

So, so find the area, you would have to multiply 5 by the length. Let's call the length "x".

The equation to solve this problem would be:

5x - 75

Now we can solve the equation...

Divide both sides by 5...

5x / 5 = 75 / 5

x = 15

Since x is equal to 15, that means that the length is 15, because we said that the length is equal to x.

Length = x = 15

Answer 2

Answer: 15 cm

Step-by-step explanation:

The formula for calculate the area of a rectangle is:

$A=l*w$

Where "l" is the lenght and "w" is the width.

You know that the area of this rectangle is 75 square centimeters and the width is 5 centimeters. Then, you can substitute these values into the formula $A=l*w$ and solve for the lenght. Then you get:

$75cm^2=l(5cm)\\\\\frac{75cm^2}{5cm}=l\\\\l=15cm$

Therefore, the lenght of the rectangle is 15 centimeters.
