Answer:

  • Area = -20x + 100
  • Perimeter = -4x + 40

Step-by-step explanation:

Given rectangle with

  • Length l = - 2x + 10
  • Width w = 10

To find

  • Area
  • Perimeter

Solution

  • A = lw
  • A = (-2x + 10)*10 = -20x + 100
  • P = 2(l +w)
  • P = 2( -2x + 10 + 10) = 2( -2x + 20) = -4x + 40
