P=2W+2L 256=2W+2(3W) 256=2W+6W 256=8W Divide by 8 on both sides 32=W
256 = (16)2 256 = (2)8
4m2-256 = 0 Add 256 to both sides: 4m2 = 256 Divide both sides by 4: m2 = 64 Square root both sides to find the value of m: m = 8 Alternatively, if 4m is to be squared, and not just the m: (4m)2 - 256 = 0 16m2 - 256 = 0 16m2 -256 + 256 = 256 16m2 = 256 16m2/16 = 256/16 m2 = 16 √m2 = √16 m = ±4
