- <span> 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</span>²
"A" is the area of the square.<span> "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</span>² <span> A=224 mm</span>² <span> 4. Now, you must substitute the value A=224 mm</span>² into the formula A=S² and clear "S": <span> A=S</span>² <span> S=</span>√A <span> S=</span>√(224 mm²) <span> S=15 mm
