What is its perimeter?This question is from textbook algebra 1 Answer by nerdybill(6962)   (Show Source): You can put this solution on YOUR website!you can find the perimeter of rectangle if you subtract the width from the length, add 7 inches, and multiply the result by 4. d.If the rectangle width is 8 inches, what is the length? What is its perimeter? . Let x = length and p = perimeter . Because we have two variables, we'll need two equations. . from the statement of the problem we get: p = (x-8 + 7)4 from standard definition of perimeter: "twice width plus length" p = 2(8+x) . Solving for x: 2(8+x) = (x-8 + 7)4 16+2x = (x-1)4 16+2x = 4x-4 16 = 2x-4 20 = 2x 10 inches = x (length) . Perimeter: p = 2(8+x) p = 2(8+10) p = 2(18) p = 36 inches (perimeter)
