Width = X Length = 3X Four sides to the perimeter: x + x + 3x + 3x = 8x 8x = 22 x = 2.75 3x = 8.25 The length is 8.25.
Length = 3x - 2Width = x + 4Area = (length) times (width) = (3x - 2) (x + 4) = 3x2 + 10x - 8
Let x be the width of the rectangle. Then the length is 3x. The area of the rectangle is 3x * x = 3x^2, which also has to be 48. Solving for x, we get that the width is 4, and the length is 12.
6x2+19x+10 = (2x+5)(3x+2) Length = 2x+5 Width = 3x+2
angles dont have lengths, but degrees. it s an equilateral triangle ( length 3X the same, angle 3X 60°)
