nd 6 are labeled. 4 tiles are in the Factor 2 spot: 1 is labeled x and 3 are labeled. 28 tiles are in the Product spot: 1 is labeled x squared, 9 are labeled x, 9 are labeled , and 9 are labeled negative. An algebra tile configuration. 5 tiles are in the Factor 1 spot: 1 is labeled x and 4 are labeled. 3 tiles are in the Factor 2 spot: 1 is labeled x and 2 are labeled. 15 tiles are in the Product spot: 1 is labeled x squared, 6 are labeled x, and 8 are labeled. An algebra tile configuration. 6 tiles are in the Factor 1 spot: 1 is labeled x and 5 are labeled. 4 tiles are in the Factor 2 spot: 1 is labeled x and 3 are labeled. 24 tiles are in the Product spot: 1 is labeled x squared, 8 are labeled x, 9 are labeled , and 6 are labeled negative. An algebra tile configuration. 9 tiles are in the Factor 1 spot: 1 is labeled x and 8 are labeled. 2 tiles are in the Factor 2 spot: 1 is labeled x and 1 is labeled. 18 tiles are in the Product spot: 1 is labeled x squared, 9 are labeled x, and 8 are labeled.
Length = 5x width = x area = 125 A = L*W 125 = (5x)(x) 125 = 5x^2 125/5 = x^2 25 = x^2 sqrt{25} = sqrt{x^2} 5 = x The width is 5 feet. The length is 5 times 5 feet or 25 feet. To find the perimeter, we use P = 2L + 2W. P = 2(25) + 2(5) P = 50 + 10 P = 60 feet. Done!
