@ezwin.academy: PSLE Unofficial - Finding the Area of a Cut-Out Square How can a 54 cm perimeter difference help you find the area of a tiny cut-out square? Rearrange the edges to see that the extra length equals two sides of the large square. Then use the area of the original rectangle, Figure 2, and the large square to find the four identical cut-outs. Each small square has an area of 121 cm². #MathTips #AreaAndPerimeter #SingaporeMath
