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.
- 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
