Answers:

14 + 18 ÷ 2 x 18 – 7 = 169

  • 14 + 9 * 18 - 7
  • 14 + 162 - 7
  • 169

60 – 9 x 8 ÷ 8 x 6 = 6

  • 60 - 72 / 8 * 6
  • 60 + -216/4
  • 60 - 54
  • 6

15 x 10 + 12 ÷ 3 + 9 = 163

  • 150 + 12 / 3 + 9
  • 150 + 4 + 9
  • 163

(10 ÷ 5)3 + 100 – 9 x 11 = 7

  • 2 * 3 + 100 - 9 * 11
  • 6 + 100 - 99
  • 7

8 x 4 + 9 – 9 + 18 = 50

  • 32 + 9 - 9 + 18
  • 41 - 9 + 18
  • 32 + 18
  • 50

3 x 8 x 2 – 42 + 5 = 11

  • 24 * 2 - 42 + 5
  • 48 - 42 + 5
  • 11

myrzilka [38]
Call the width ' W '.
Then the length is W + 55

Perimeter (distance all around) = W + (W+55) + W + (W+55) = 4W + 110

4W + 110 = 1,310

4W = 1,200

W = 300-ft

Length = W + 55 = 355-ft
