Answer:
160
Explanation:
The perimeter contains for side. On one side, the width is 51. That means on the other side, the width must also be 51. 51 + 51 = 102. The length of one side is 74, so the length of the other side must also be 74. 74 + 74 = 148. Now, to get our final answer of the perimeter of the whole floor we must add the length and width of the floor. 148 + 102 = 160. Therefore, the perimeter of the floor is 160.
