网考网参考答案：E
网考网解析：
To determine the length of the unmeasured side, divide the figure into a rectangle with length 65 and a right triangle. If the height of the triangle is 40 and the hypotenuse is 50, then by the Pythagorean theorem the other leg is 30; the top segment of the rectangle is 65 like its opposite side, so the unmeasured side is 30+65=95. The perimeter is the sum of the sides: 95+40+65+50=250. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
