What is the length of each side of a square that has the same area as a rectangle that is 14 mm long and 16 mm wide? Round to the nearest whole number.

1. You have the following information:

- The square has the same area as a rectangle.

- The dimensions of the rectangle are: 14 mm long and 16 mm wide.

2. You must use the formula for calculate the area of a square, which is shown below:

A=S ²

"A" is the area of the square.

"S" is the lenght of the side of the square. (It is important to remember that the sides of a squre have equals lenghts.

3. The square and the rectangle have the same area. Therefore:

Arectangle = (14 mm) (16 mm)

Arectangle=224 mm ²

A=224 mm ²

4. Now, you must substitute the value A=224 mm ² into the formula A=S² and clear "S":

A=S ²

S = √A

S = √ (224 mm²)

S=15 mm

The answer is: 15 mm
