[計量] 兩題計量請教
1.
The decorating committee for a dance plans to fringe
the 3-inch-wide end of a streamer by making small cuts
every 1/16 inch. How many cuts must be made to fringe
the end?
答案：47（為什麼不是48呢？）
2.第二題比大小更慘，我完全看不懂題意：
A thin strip of binding 30 feet long just fits around
the perimeter of a rectangular rug that covers an area
of 54 square feet.
A B
The length of the
longer side of the 10 feet
rug
答案：B 比較大
謝謝大家
