So if its 224 square feet and the width if 14 feet the length should be 14 also I think lol
Here , imagine a square put 224 inside it for the area , then put down 14 on top and bottom because its the width , multiple 14×14=56+140=196+14=210+14=224
And the last 14's are the length which u have to add
Im not sure if that made any sence lol but I hope it did .
