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=S²
"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 mm²
A=224 mm²
4. Now, you must substitute the value A=224 mm² into the formula A=S² and clear "S":
A=S²
S=√A
S=√(224 mm²)
S=15 mm
The answer is: 15 mm
